                             ITEM 1.  BUSINESS


OVERVIEW

TECHNE Corporation (the Company) is a holding company which has two wholly-
owned operating subsidiaries:  Research and Diagnostic Systems, Inc. (R&D
Systems) located in Minneapolis, Minnesota and R&D Systems Europe Ltd. (R&D
Europe) located in Abingdon, England.  R&D Systems is a specialty
manufacturer of biological products.  Its two major operating segments are
hematology controls, which are used in hospital and clinical laboratories to
check the performance of blood analysis instruments, and biotechnology
products, including purified proteins (cytokines) and antibodies which are
sold exclusively to the research market and assay kits which are sold to the
research and clinical diagnostic markets.  R&D Europe distributes R&D
Systems' biotechnology products in Europe.  R&D Europe has a German sales
subsidiary, R&D Systems GmbH (R&D GmbH) and a sales office in France.

R&D Systems was founded and incorporated in 1976 in Minneapolis, Minnesota
and was acquired by the Company in 1985.  In 1977, R&D Systems introduced its
first product, a platelet-rich-plasma control.  In 1981, R&D Systems was the
second manufacturer in the world to release a whole blood control with
platelets, thereby establishing itself as one of the leaders in the field of
hematology control products manufacturing.  Subsequently, R&D Systems has
developed several types of hematology controls designed to keep pace with the
technology of the newest models of hematology instruments.  These products
are sold throughout the United States directly by R&D Systems and in many
foreign countries through distributors.

In 1985, R&D Systems entered the research reagent market with its first
cytokine, transforming growth factor-beta (TGF-beta).  Cytokines are
specialized protein molecules that stimulate or suppress various cellular
functions in the body.  Cytokines are in demand by biomedical researchers who
want to learn more about their diverse effects.  Encouraged by its early
success in the cytokine market, R&D Systems formed a biotechnology division
in fiscal 1986 with the goal of producing a wide range of cytokines through
genetic engineering.  Recombinant DNA technology offers several advantages
over extraction of these proteins from natural sources, including lower
production cost and potentially unlimited supply.

In fiscal 1992, R&D Systems purchased Amgen Inc.'s research reagent and
diagnostic assay kit business.  With this purchase, R&D Systems obtained
Amgen's Erythropoietin (EPO) kit, the Company's first enzyme-linked
immunosorbent assay (ELISA) kit for a cytokine that had been cleared by the
U.S. Food and Drug Administration (FDA) for clinical diagnostic use.

In fiscal 1994, the Company acquired its European biotechnology distributor,
British Bio-technology Products Ltd. (renamed R&D Systems Europe Ltd.) from
British Bio-technology Group plc.  R&D Europe distributes biotechnology
products developed and manufactured by R&D Systems.

Between fiscal 1998 and 2000 and in 2004, the Company made equity investments
in the preferred stock of ChemoCentryx, Inc. (CCX), a technology and drug
development company.  The Company currently holds approximately 19.9% of the
outstanding stock of CCX.  In addition to the equity investment and joint
research efforts, the Company obtained research and diagnostic market rights
to all products discovered or developed by CCX.

                                      3


In fiscal 1999, R&D Systems purchased Genzyme Corporation's (Genzyme)
research products business.  This acquisition established R&D Systems as the
world's leading supplier of research and diagnostic cytokine products.

In fiscal 2002, the Company made an equity investment of $3 million and
entered into a research and license agreement with Discovery Genomics, Inc.
(DGI) of Minneapolis, Minnesota.  DGI holds licenses from the University of
Minnesota to develop technologies used for functional genomics and the
discovery of drugable targets.  The Company currently holds a 38% equity
interest in DGI and warrants to acquire additional equity.  The Company also
received the rights to develop antibodies and immunoassay kits for proteins
discovered by DGI and an exclusive, royalty free license to sell such
products in the research market.  During the fourth quarter of fiscal 2004,
the Company determined that its investment in DGI was other than temporarily
impaired and wrote off the remaining net investment of $1.5 million.

In January 2004, the Company purchased a 10% interest in Hemerus Medical, LLC
(Hemerus) for $3 million.  Hemerus was formed in March 2001 and has acquired
and is developing technology for the separation of leukocytes from blood and
blood components.

In July 2005, the Company acquired Fortron Bio Science, Inc. and BiosPacific,
Inc. for an aggregate $20 million in cash.  Fortron develops and manufactures
antibodies and BiosPacific is a worldwide supplier of biologics to
manufacturers of in vitro immunodiagnostic kits.  The acquisitions will help
the Company expand into the diagnostic market by offering research reagents
that may have future diagnostic application and/or developing products
specifically for diagnostic markets.


THE MARKET

The Company, through its two operating subsidiaries, manufactures and sells
products for the clinical diagnostics market (hematology controls and
calibrators) and the biotechnology research and clinical diagnostics market
(cytokines, assays and related products).  In fiscal 2005, 2004 and 2003, R&D
Systems' Hematology Division revenues accounted for approximately 9%, 11% and
11%, respectively, of consolidated revenues.  Revenues from R&D Systems'
Biotechnology Division were 62%, 62% and 63% and revenues from R&D Europe
were 29%, 27% and 26% of consolidated revenues for fiscal 2005, 2004 and
2003, respectively.


                       Biotechnology Products

R&D Systems is the world's leading supplier of cytokines and cytokine-related
reagents to the biotechnology research community.  These valuable proteins
exist in minute amounts in different types of cells and can be extracted from
these cells or made through recombinant DNA technology.  In 1985, R&D Systems
introduced its first cytokine and continues to add to this product line.  The
first cytokines were extracted from natural sources (human and porcine
platelets and bovine brain).  Currently almost all of cytokines are produced
by recombinant DNA technology.

The growing interest by academic and commercial researchers in cytokines
exists because of the profound effect a tiny amount of a cytokine can have on
the cells and tissues of the body.  Cytokines are intercellular messengers.
They act as signals by interacting with specific receptors on the affected
cells and trigger events that can lead to significant changes in a cell,
tissue or organism.  For example, cytokines can signal a cell to
differentiate, i.e., to acquire the features necessary for it to take on a
more specialized task.  Another example of cytokine action is the key role
played in stimulating cells surrounding a wound to grow and divide, to
attract migratory cells to the injury site and mediate the healing process.

                                    4


In recent years, R&D Systems' Biotechnology Division has also added enzymes
and intracellular cell signaling reagents to its product portfolio.   Enzymes
are biological catalysts that accelerate a variety of chemical reactions in
cells.  Most enzymes, including proteases, kinases and phosphatases, are
proteins that modify the structure and function of other proteins.  Many
enzymes are important markers and therapeutic targets for diseases such as
cancer, Alzheimer's, arthritis, diabetes, hypertension, obesity, AIDS and
SARS.

The Biotechnology Division markets its cytokine assay kits under the
tradename Quantikine(r).  These kits are used by scientific researchers to
quantify the level of a specific cytokine in a sample of serum, plasma or
other biological fluid.  Cytokine quantification is performed for basic
research and in pharmaceutical discovery and development programs.

R&D Systems currently manufactures and sells over 8,500 biotechnology
products.

Current Biotechnology Products

Cytokines and Enzymes.  Cytokines, extracted from natural sources or
produced using recombinant DNA technology, are manufactured to the highest
purity.  Enzymes and related factors including enzyme substrates and
inhibitors are highly purified and characterized to ensure the highest
biological activity.

Antibodies.  Antibodies are proteins produced by the immune system of an
animal that specifically recognize and bind to target molecules.  The
Company's polyclonal antibodies are produced in animals (primarily goats)
and purified from the animals' blood.  Monoclonal antibodies are made by
immortalized cell lines derived from the individual antibody producing
cells of a rodent.  Monoclonal antibodies are secreted from these cell
lines during cell culture and purified from the cell culture medium.

Assay Kits.  This product line includes R&D Systems' human and animal
Quantikine kits which allow research scientists to quantify the amount of
a specific analyte (cytokine, adhesion molecule, enzyme, etc.)  in a
sample of serum or other biological fluids.

Clinical Diagnostic Kits.  The EPO kit, acquired from Amgen Inc. in fiscal
1992, was the first diagnostic assay for which R&D Systems received FDA
marketing clearance.  R&D Systems also has received FDA marketing
clearance for its transferrin receptor (TfR) and Beta2-microglobulin kits.

Flow Cytometry Products.  This product line includes R&D Systems' labeled
antibodies and Fluorokine(r) kits, which are used to measure the presence or
absence of cell surface receptors for specific cytokines by flow
cytometry.

Intracellular Cell Signaling Products.  This diverse product line provides
reagents to study apoptosis (programmed cell death) and to elucidate
signal transduction pathways.  Products include antibodies, phospho-
specific antibodies, antibody protein arrays, active caspases, kinases,
and phosphatases, and ELISA assays to quantitate and measure the activity
of apoptotic and signaling molecules.



                      Hematology Controls and Calibrators

Hematology controls and calibrators, manufactured by and marketed through the
Hematology Division of R&D Systems, are products composed of the various
cellular components of blood which have been stabilized.  Proper diagnosis of
many illnesses requires a thorough and accurate analysis of a patient's blood
cells, which is usually done with automated or semi-automated hematology
instruments.  Controls and calibrators produced by the Hematology Division
ensure that these instruments are performing accurately and reliably.

                                   5


Blood is composed of plasma, the fluid portion of which is mainly water, and
blood cells, which are suspended in the plasma.  There are three basic types
of blood cells:  red cells, white cells and platelets.   Hemoglobin in red
cells transport oxygen from the lungs throughout the body.  White cells
defend the body against foreign invaders.  Platelets serve as a "plug" to
stem blood flow at the site of an injury by initiating a complex series of
biochemical reactions that lead to the formation of a clot.

These fundamental components (red cells, white cells and platelets) differ
widely in size and concentration.  As noted above, hematology controls are
used in automated and semi-automated cell counting analyzers to make sure
these instruments are counting blood cells in patient samples accurately.
One of the most frequently performed laboratory tests on a blood sample is a
complete blood count or CBC.  Doctors use this test in disease screening and
diagnosis.  More than one billion of these tests are done every year, the
great majority with cell counting instruments.  In most laboratories the CBC
consists of the white cell count, the red cell count, the hemoglobin reading,
and the hematocrit reading (the percent of red cells in a volume of whole
blood after it has been centrifuged).  Also included in a CBC test is the
differential, which numbers and classifies the different types of white
cells.

These and other characteristics or "parameters" of a blood sample can be
measured by automated or semi-automated cell counters.  The number of
parameters measurable in a blood control product depends on the type and
sophistication of the instrument for which the control is designed.
Ordinarily, a hematology control is used once to several times a day to make
sure the instrument is reading accurately.  In addition, most instruments
need to be calibrated periodically.  Hematology calibrators are similar to
controls, but go through additional testing to ensure that the calibration
values assigned are extremely accurate and can be used to calibrate the
instrument.

The Hematology Division of R&D Systems offers a wide range of hematology
controls and calibrators for both impedance and laser type cell counters.
R&D Systems believes its products have improved stability and versatility and
a longer shelf life than most of those of its competitors.  The Hematology
Division supplies hematology control products for use as proficiency testing
materials by laboratory certifying authorities of a number of states and
countries.

Current Retail Hematology Products

Whole Blood CBC Controls/Calibrators.  The Hematology Division of R&D
Systems currently produces controls and calibrators for the following
brands of analyzers: Abbott Diagnostics, Beckman Coulter, Bayer Technicon
and Sysmex.

Linearity and Reportable Range Controls.  These products provide a means
of assessing the linearity of hematology analyzers for white blood cells,
red blood cells, platelets and reticulocytes (immature red blood cells).
Because hematology analyzers are single point calibrated, these products
allow users to determine and validate the reportable range of an
instrument.

Whole Blood Reticulocyte Controls.  These controls are designed for manual
and automated counting of reticulocytes.

Whole Blood Flow Cytometry Controls.  These products are controls for flow
cytometry instruments.  These instruments are used to identify and
quantify white blood cells by their surface markers.

Whole Blood Glucose/Hemoglobin Control.  This product is designed to
monitor instruments which measure glucose and hemoglobin in whole blood.

                                   6


Erythrocyte Sedimentation Rate Control.  This product is designed to
monitor erythrocyte (red blood cell) sedimentation rate tests.

Multi-Purpose Platelet Reference Controls.  These products, Platelet-Trol(r)
II and Platelet-Trol Extended, are designed for use by automated and semi-
automated analyzers.


PRODUCTS UNDER DEVELOPMENT

R&D Systems is engaged in ongoing research and development in all of its
major product lines:  controls and calibrators (Hematology Division) and
cytokines, antibodies, assays and related products (Biotechnology Division).
The Company believes that its future success depends, to a large extent, on
the ability to keep pace with changing technologies and markets.  At the same
time, the Company continues to examine its production processes to ensure
high quality and maximum efficiency.

R&D Systems' Biotechnology Division is planning to release new cytokines,
antibodies and cytokine assay kits in the coming year.  All of these products
will be for research purposes only and therefore do not require FDA
clearance.  R&D Systems' Hematology Division has developed several new
control products in fiscal 2005 and is continuously working on product
improvements and enhancements.  However, there is no assurance that any of
the products in the research and development phase can be developed or, if
developed, can be successfully introduced into the marketplace.

Included in consolidated research and development expense through fiscal 2004
were the Company's share of equity method losses by CCX and DGI and Hemerus,
companies in which the Company has invested.  Research and development
expense was as follows (in thousands):

BUSINESS RELATIONSHIPS

The Company has invested in the Preferred Stock (Series A and B) of
ChemoCentryx, Inc. (CCX).  CCX is a technology and drug development company
working in the area of chemokines.  Chemokines are cytokines which regulate
the trafficking patterns of leukocytes, the effector cells of the human
immune system.  In conjunction with the equity investment and joint research
efforts, the Company obtained exclusive worldwide research and diagnostic
marketing rights to chemokine proteins, antibodies and receptors discovered
or developed by CCX.  Through April 2004, the Company held 26% of the
outstanding stock of CCX and accounted for the investment under the equity
method of accounting.  In May and June, 2004, CCX obtained $38.1 million in
financing through the issuance of approximately 14.7 million shares of
Preferred (Series B) Stock.  The financing included a $5.1 million investment
by the Company.  After the financing, the Company holds a 19.9% equity
interest in CCX.  The Company then evaluated the cost versus equity method of
accounting for its investment in CCX and determined that it does not have the
ability to exercise significant influence over the operating and financial
policies of CCX and therefore, after April 2004, accounted for its investment
on a cost basis. The Company's net investment in CCX was $5.1 million at June
30, 2005 and 2004. The Company has been issued warrants for 1.7 million
shares of CCX Preferred Stock (Series A) at $5.00 per share, which expire on
December 31, 2005.

                                    7


In fiscal 2002, the Company made an equity investment of $3 million (1.5
million shares) and entered into a research and license agreement with
Discovery Genomics, Inc. (DGI) of Minneapolis, Minnesota.  DGI holds licenses
from the University of Minnesota to develop technologies used for functional
genomics and the discovery of drugable targets.  The Company currently holds
a 38% equity interest in DGI and warrants to acquire an additional 1.5
million shares at $2.50 per share.  The Company also received the rights to
develop antibodies and immunoassay kits for proteins discovered by DGI and an
exclusive, royalty-free license to sell such products in the research market.
The Company's investment is accounted for under the equity method of
accounting.  During the fourth quarter of fiscal 2004, the Company determined
that its investment in DGI was other than temporarily impaired and wrote off
the remaining net investment of $1.5 million.

On January 1, 2004, the Company purchased a 10% interest in Hemerus Medical,
LLC (Hemerus) for $3 million. Hemerus was formed in March 2001 and has
acquired and is developing technology for the separation of leukocytes from
blood and blood components. Leukoreduced blood is important in blood
transfusion. Hemerus owns two patents and has several patent applications
pending and is currently pursuing FDA clearance to market its products in the
U.S. In parallel with this investment, R&D Systems entered into a Joint
Research Agreement with Hemerus. The research will involve joint projects to
explore the use of Hemerus' filter technology to applications within R&D
Systems' Hematology and Biotechnology Divisions. Such applications, if any,
may have commercial potential in other laboratory environments. The Company
accounts for its investment in Hemerus under the equity method of accounting,
as it is a limited liability corporation.  The Company's net investment in
Hemerus was $2.6 million and $2.9 million at June 30, 2005 and 2004,
respectively.

Original Equipment Manufacturer (OEM) agreements represent the largest market
for hematology controls and calibrators made by R&D Systems.  In fiscal 2005,
2004 and 2003, OEM contracts accounted for $6.8 million, $7.7 million and
$7.2 million, respectively, or 4%, 5% and 5% of total consolidated revenues.


GOVERNMENT REGULATION

All manufacturers of hematology controls and calibrators are regulated under
the Federal Food, Drug and Cosmetic Act, as amended.  All of R&D Systems'
hematology control products are classified as "In Vitro Diagnostic Products"
by the FDA.  The entire hematology control manufacturing process, from
receipt of raw materials to the monitoring of control products through their
expiration date, is strictly regulated and documented.  FDA inspectors make
periodic site inspections of the Hematology Division's control operations and
facilities.  Hematology control manufacturing must comply with Quality System
Regulations (QSR) as set forth in the FDA's regulations governing medical
devices.

Three of R&D Systems' immunoassay kits, EPO, TfR and Beta2-microglobulin,
have FDA clearance to be sold for clinical diagnostic use.  R&D Systems must
comply with QSR for the manufacture of these kits.  Biotechnology products
manufactured in the United States and sold for use in the research market do
not require FDA clearance.

Some of R&D Systems' research groups use small amounts of radioactive
materials in the form of radioisotopes in their product development
activities.  Thus, R&D Systems is subject to regulation by the US Nuclear
Regulatory Commission (NRC) and has been granted an NRC license due to expire
in April 2006.  The license is renewable annually.  R&D Systems is also
subject to regulation and inspection by the Department of Health of the State
of Minnesota for its use of radioactive materials.  It has been granted a
certificate of registration, which is renewable annually, by the Minnesota
Department of Health.  The current certificate expires April 1, 2006.  R&D
Systems has had no difficulties in renewing these licenses in prior years and
has no reason to believe they will not be renewed in the future.  If,
however, the licenses were not renewed, it would have minimal effect on R&D
Systems' business since there are other technologies the research groups
could use to replace radioisotopes.

AVAILABILITY OF RAW MATERIALS

The primary raw material for the Company's hematology controls is whole
blood.  Human blood is purchased from commercial blood banks and porcine and
bovine blood is purchased from nearby meat processing plants.  After raw
blood is received, it is separated into its components, processed and
stabilized.  Although the cost of human blood has increased owing largely to
the requirement that it be tested for certain diseases, the higher cost of
these materials has not had a serious adverse effect on the Company's
business.  R&D Systems does not perform its own testing as the supplier tests
all human blood purchased.  R&D Systems' Biotechnology Division develops and
manufactures the majority of its cytokines from synthetic genes developed in-
house, thus significantly reducing its reliance on outside resources.  R&D
Systems typically has several outside sources for all critical raw materials
necessary for the manufacture of products.


PATENTS AND TRADEMARKS

R&D Systems owns patent protection for certain hematology controls.  R&D
Systems may seek patent protection for new or existing products it
manufactures.  No assurance can be given that any such patent protection will
be obtained.  No assurance can be given that R&D Systems' products do not
infringe upon patents or proprietary rights owned or claimed by others,
particularly for genetically engineered products. R&D Systems has not
conducted a patent infringement study for each of its products.  See Item 3
Legal Proceedings below.

R&D Systems and R&D Europe have a number of licensing agreements with patent
holders under which they have the non-exclusive right to patented technology
or the non-exclusive right to manufacture and sell certain patented cytokine
and cytokine related products to the research market.  For fiscal 2005, 2004
and 2003, total royalties expensed under these licenses were approximately
$2.6 million, $2.3 million and $2.3 million, respectively.

R&D Systems has obtained federal trademark registration for certain of its
hematology controls and biotechnology product groups.  R&D Systems believes
it has common law trademark rights to certain marks in addition to those
which it has registered.


SEASONALITY OF BUSINESS

Sales of products by R&D Systems and R&D Europe, particularly R&D Europe,
historically experience a slowing of sales or of the rate of sales growth
during the summer months.  R&D Systems also usually experiences a slowing of
sales during the Thanksgiving to New Year holiday period.  The Company
believes this slowing is a result of vacation schedules in Europe and Japan
and of academic schedules in the United States.

                                     9


SIGNIFICANT CUSTOMERS

No single customer accounted for more than 10% of total revenues during
fiscal 2005, 2004 or 2003.


BACKLOG

There was no significant backlog of orders for the Company's products as of
the date of this report or as of a comparable date for fiscal 2004.  The
majority of the Company's biotechnology products are shipped within one day
of receipt of the customers' order.  The majority of hematology products are
shipped based on a preset, recurring schedule.


COMPETITION

The worldwide market for cytokines and research diagnostic assay kits is
being supplied by a number of biotechnology companies, including BD
Biosciences, BioSource International, PeproTech, Inc., Sigma Chemical Co.,
Amersham Biosciences, Fisher Scientific and EMD Biosciences, Inc.  R&D
Systems believes that it is the leading worldwide supplier of cytokine
related products in the research marketplace.  R&D Systems believes that the
expanding line of its products, their recognized quality, and the growing
demand for these rare and versatile proteins, antibodies and assay kits, will
allow the Company to remain competitive in the growing biotechnology research
and diagnostic market.

Competition is intense in the hematology control business.  The first control
products were developed in response to the rapid advances in electronic
instrumentation used in hospital and clinical laboratories for blood cell
counting.  Historically, most of the instrument manufacturing companies made
controls for use in their own instruments.  With rapid expansion of the
instrument market, however, a need for more versatile controls enabled non-
instrument manufacturers to gain a foothold.  Today the market is comprised
of manufacturers of laboratory reagents, chemicals and coagulation products
and independent control manufacturers in addition to instrument
manufacturers.  The principal hematology control competitors of R&D Systems'
retail products are Beckman Coulter, Inc., Sysmex, Streck Laboratories,
Abbott Diagnostics, Bio-Rad Laboratories and Bayer Technicon.  R&D Systems
believes it is the third largest supplier of hematology controls in the
marketplace behind Beckman Coulter and Streck Laboratories.


EMPLOYEES

R&D Systems had 489 full-time and 43 part-time employees as of June 30, 2005.
R&D Europe had 49 full-time and 17 part-time employees as of June 30, 2005,
including 9 full-time and 2 part-time at R&D Europe's sales subsidiary in
Germany.


ENVIRONMENT

Compliance with federal, state and local environmental protection laws in the
United States, United Kingdom and Germany had no material effect on R&D
Systems or R&D Europe in fiscal 2005.

improvements, equipment and deposits on real estate.


RISK FACTORS

The following risk factors should be read carefully in connection with
evaluation the Company's business and any forward-looking statements made in
this Report and elsewhere.  Any of the following risks could materially
adversely affect the Company's business, operating results and financial
condition.

The Company's biotechnology products are sold primarily to research
scientists at pharmaceutical and biotechnology companies and at university
and government research institutions. Changes in spending on research by such
companies and in funding of such universities and institutions by government,
including the National Institutes of Health, affects the revenues and
earnings of the Company. The Company carries essentially no backlog of orders
and changes in the level of orders received and filled daily can cause
fluctuations in quarterly revenues and earnings.

Approximately one quarter of the Company's sales are made through its
European subsidiary, R&D Systems Europe, which makes its sales in foreign
currencies. The Company's revenues and earnings are, therefore, affected by
fluctuations in currency exchange rates.

The biotechnology industry is subject to rapid and significant technological
change. While the hematology controls industry historically has been less
subject to rapid change, it too is evolving and is impacted significantly by
changes in the automated testing equipment offered by instrument
manufacturers. Competitors of the Company are numerous and include, among
others, specialized biotechnology firms, medical laboratory instrument and
equipment manufacturers and disposables suppliers, major pharmaceutical
companies, universities and other research institutions. There can be no
assurance that the Company's competitors will not succeed in developing
technologies and products that are more effective than any which have been or
are being developed by the Company or that would render the Company's
technologies and products obsolete or noncompetitive.

The Company's success will depend, in part, on its ability to obtain licenses
and patents, maintain trade secret protection and operate without infringing
the proprietary rights of others. The Company has obtained and is negotiating
licenses to produce a number of cytokines and related products claimed to be
owned by others. Since the Company has not conducted a patent infringement
study for each of its products, it is possible that products of the Company
may unintentionally infringe patents of third parties or that the Company may
have to alter its products or processes, pay licensing fees or cease certain
activities because of patent rights of third parties, thereby causing
additional unexpected costs and delays which may have a material adverse
effect on the Company.

                                     11


The Company's expansion strategies, which include internal development of new
products, collaborations, investments in joint ventures and companies
developing new products related to the Company's business, and the
acquisition of companies for new products and additional customer base, carry
risks that objectives will not be achieved and future earnings will be
adversely affected. Under the equity method of accounting, a percentage of
the losses of certain companies in which the Company invests will be reported
as losses of the Company. The Company may not have control of the expense
levels of such companies and their losses may be greater than those
anticipated by the Company. Additionally, if the Company determines that its
investment in such companies is "other than temporarily" impaired, the
Company may write off its entire investment in such company.

Ongoing research and development activities and the production and marketing
of certain of the Company's products are subject to regulation by numerous
governmental authorities in the United States and other countries. The
approval process applicable to clinical diagnostic products of the type that
may be developed by the Company may take a year or more. Delays in obtaining
approvals could adversely affect the marketing of new products developed by
the Company.

Recruiting and retaining qualified scientific and production personnel to
perform research and development work and product manufacturing are critical
to the Company's success. The Company's anticipated growth and its expected
expansion into areas and activities requiring additional expertise will
require the addition of new personnel and the development of additional
expertise by existing personnel. The failure to attract and retain such
personnel could adversely affect the Company's business.

                             ITEM 2.  PROPERTIES

The Company owns the facilities its R&D Systems subsidiary occupies in
Minneapolis, Minnesota.  The R&D Systems complex currently includes 365,000
square feet of administrative, research and manufacturing space in three
adjoining buildings.

In fiscal 2002, the Company purchased property adjacent to its Minneapolis
facility for approximately $8.9 million.  The Company has renovated this
property and plans to lease approximately 70% of the 176,000 square foot
building as retail and office space and use the remainder as warehouse and
storage space.  The Company has constructed a link to connect this building
to its current facility.  The Company will begin finishing the 78,000 square
foot link, to be used primarily for laboratory space, in fiscal 2006.

On January 3, 2005, the Company acquired property adjacent to its Minneapolis
facility for $10.4 million.  Included in long-lived assets at June 30, 2004
was $2 million deposited in escrow in fiscal 2002 for the property. A portion
of the property is currently leased to third parties and the Company plans to
continue to lease out the building until the space is needed for its own
operations.

In fiscal 2003, the Company purchased approximately 649 acres of farmland,
including buildings, in southeast Minnesota for $2.7 million.  A portion of
the land and buildings are being leased to third parties as cropland and for
a dairy operation. The remaining property is used by the Company to house
goats used for polyclonal antibody production.  In fiscal 2005 and 2004, the
Company constructed additional buildings on this site for $.8 million and
$2.3 million, respectively.

Rental income from the above properties was $750,000, $131,000 and $72,000 in
fiscal 2005, 2004 and 2003, respectively.

R&D Europe leases approximately 17,000 square feet in a building in Abingdon,
England.  Base rent was $473,000 in fiscal 2005.

R&D GmbH leases approximately 2,300 square feet as a sales office in
Wiesbaden-Nordenstadt, Germany.  Base rent was $42,000 in fiscal 2005.

The Company believes the owned and leased property discussed above are
adequate to meet its occupancy needs in the foreseeable future.


                        ITEM 3.  LEGAL PROCEEDINGS

On June 13, 2003, the Company submitted to the U.S. Patent and Trademark
Office ("PTO") a "Request for Interference" to initiate an action between the
Company and Streck Laboratories, Inc. regarding certain patents issued to
Streck.  The Streck patents relate to the addition of reticulocytes to
hematology controls.  The Company has reason to believe that it invented the
invention(s) claimed in the Streck patents before Streck and is seeking a
decision by the PTO that the Company is entitled to a patent covering the
invention(s) and that the Streck patent is invalid.


            ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matter was submitted to a vote of the Company's security holders during
the fourth quarter of the Company's 2005 fiscal year.

6/1/05-6/30/05       0          --              0            $6.8 million

In May 1995, the Company announced a plan to purchase and retire its Common
Stock.  Repurchases of $40 million were authorized as follows:  May 1995 - $5
million; April 1997 - $5 million; January 2001 - $10 million; October 2002 -
$20 million.  The plan does not have an expiration date.

On February 17, 2005, the Board of Directors of the Company approved the
repurchase of approximately 2.9 million shares of its common stock under an
accelerated stock buyback ("ASB") transaction for an initial value of
approximately $100 million ($34.45 per share). The transaction was completed
under a privately negotiated contract with an investment bank.  The ASB
agreement is subject to a market price adjustment provision based upon a
volume weighted average price during the nine-month period ending in December
2005.  In December 2005, the Company will, at its option, settle the ASB
agreement in cash or shares of the Company's common stock. At an average
market price of $43.50, which approximates the average market price from the
transaction date through June 30, 2005, the settlement amount for the
contract would be approximately $18.6 million or about 428,000 shares. The
purchase price adjustment will be reflected in stockholders equity at the
time of settlement.

Approximately 1.8 million of the shares repurchased are subject to a collar,
which effectively sets a minimum and maximum price the Company will be
obligated to pay for such shares. The collar was established in exchange for
an up-front payment of $3.5 million. The minimum and maximum price for the
1.8 million shares is approximately $39.00 and $41.00, respectively.  The
maximum additional amount that could be required to be paid related to the
shares subject to the collar is $8.5 million or about 215,000 shares.  The
adjusted price of the remaining 1.1 million repurchased shares will be based
upon the difference between the volume weighted average price during the
nine-month period and the initial $34.45 per share payment. For each $1.00
change in the average market price during the nine-month period, the
Company's obligation under the uncollared portion of the agreement would
increase or decrease by $1.1 million.  Should the Company elect to settle the
ASB agreement in shares, each $1.00 increase in the average market price over
$40.00 during the nine-month period will increase the number of shares
required for settlement under the uncollared portion of the agreement, but
reduce the number of shares required by the collared portion of the contract
by a net amount of about 15,000 shares.

          ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                   CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

TECHNE Corporation (the Company) has two operating subsidiaries: Research and
Diagnostic Systems, Inc. (R&D Systems) and R&D Systems Europe Ltd. (R&D
Europe). R&D Systems, located in Minneapolis, Minnesota, has two operating
segments: its Biotechnology Division and its Hematology Division. The
Biotechnology Division develops and manufactures purified cytokines (proteins),
antibodies and assay kits which are sold to biomedical researchers and clinical
research laboratories. The Hematology Division develops and manufactures whole
blood hematology controls and calibrators which are sold to hospitals and
clinical laboratories to check the performance of hematology instruments to
assure the accuracy of hematology test results. R&D Europe, the Company's third
operating segment, located in Abingdon, England, is the European distributor of
R&D Systems' biotechnology products. R&D Europe has a sales subsidiary, R&D
Systems GmbH, in Germany and a sales office in France.


OVERALL RESULTS

Consolidated net earnings increased 24.9% for fiscal 2005 as compared to fiscal
2004. Increased net sales was the primary reason for the improvement. Net sales
increased 10.8% from fiscal 2004. A lower effective income tax rate, reduced
losses and write-offs from equity investments and increased gross margins from
78.4% to 79.4% also contributed to the improvement in net earnings. The
favorable impact on consolidated net earnings of the strengthening of the
British pound as compared to the U.S. dollar for R&D Europe results was
$868,000 for the year ended June 30, 2005.

Consolidated net earnings increased 16.6% for fiscal 2004 as compared to
fiscal 2003. The primary reasons for the increase were increased net sales and
improved gross margins. Net sales increased 11.2% from fiscal 2003 and gross
margins increased from 75.6% to 78.4%. The favorable impact on consolidated net
earnings of the strengthening of the British pound as compared to the U.S.
dollar for R&D Europe results was $1.1 million for the year ended June 30,
2004.

                           ========      ========     ========

Net sales for fiscal 2005 were $178.7 million, an increase of $17.4
million (10.8%) from fiscal 2004. Consolidated net sales in fiscal 2005 were
affected by favorable exchange rates used in converting British pounds to U.S.
dollars. Excluding the effect of foreign currency exchange rates, consolidated
net sales increased 8.9% for fiscal 2005. Biotechnology Division net sales for
fiscal 2005 increased $11.8 million (11.8%) from fiscal 2004, the majority of
which ($9.7 million) was from increased U.S. retail sales. The effect of
foreign exchange rates on R&D Europe's net sales for fiscal 2005 was an
increase of approximately $3.0 million. R&D Europe's net sales in British
pounds increased 8.9% in fiscal 2005. The decrease in Hematology Division net
sales in fiscal 2005 was the result of the reduction in sales to one OEM
customer beginning in January 2005. Sales to this customer in the second half
of fiscal 2004 were $1.4 million.

Net sales for fiscal 2004 were $161.3 million, an increase of $16.2
million (11.2%) from fiscal 2003. Consolidated net sales in fiscal 2004 were
also affected by favorable exchange rates used in converting British pounds to
U.S. dollars. Excluding the effect of foreign currency exchange rates,
consolidated net sales increased 8.4% for fiscal 2004. Biotechnology Division
net sales for fiscal 2004 increased $8.4 million (9.3%) from fiscal 2003, the
majority of which ($6.9 million) was from increased U.S. retail sales. The
effect of foreign exchange rates on R&D Europe's net sales for fiscal 2004 was
an increase of approximately $4.0 million. R&D Europe's net sales in British
pounds increased 8.0% in fiscal 2004.

                                  17


Cost of sales. The manufacturing process for proteins and antibodies has and
may continue to produce quantities in excess of forecasted usage. The Company
values its manufactured protein and antibody inventory based on a two-year
forecast. Proteins and antibody quantities in excess of the two-year usage
forecast are considered impaired and not included in the inventory value. The
value of protein and antibody inventory does not change significantly from
quarter to quarter. Protein and antibody production is generally for high-
volume products or for new products with limited initial sales. The Company
capitalizes protein and antibody costs each period in inventory, however given
the insignificant changes in these inventory balances each quarter,
substantially all manufacturing costs for proteins and antibodies, consisting
largely of wages, benefits, facility and equipment costs, are expensed each
quarter. A change in inventory value as a result of estimate changes in the
two-year forecast is reflected in cost of sales in the period of change.
Manufacturing costs and changes in inventory value for proteins and antibodies
charged to cost of sales were $6.6 million, $6.4 million and $6.7 million for
the fiscal years ended June 30, 2005, 2004 and 2003, respectively.

Gross margins, as a percentage of net sales, were as follows:

                                    YEAR ENDED JUNE 30,

Biotechnology Division       80.7%         80.4%        79.0%
R&D Systems Europe           53.2%         51.4%        41.8%
Hematology Division          46.5%         46.2%        47.2%
Consolidated                 79.4%         78.4%        75.6%

The increase in gross margin percentage in fiscal 2005 was mainly the
result of R&D Europe's gross margin increasing from 51.4% in fiscal 2004 to
53.2% as a result of favorable exchange rates between a weaker U.S. dollar and
stronger British pound.

The majority of the increase in gross margin percentage from fiscal 2003
to fiscal 2004 was the result of R&D Europe's gross margins increasing from
41.8% to 51.4%, respectively. Approximately one-half of this increase was due
to favorable exchange rates as a result of a weaker U.S. dollar to the British
pound and one-half was due to the expiration, on June 30, 2003, of a five-year,
5% royalty agreement associated with the purchase of Genzyme, Inc.'s reagent
business in fiscal 1999. R&D Europe expensed $1.8 million in fiscal 2003 under
this agreement. The Biotechnology Division gross margin percentage increase of
1.4% in fiscal 2004 from fiscal 2003, was mainly a result of changes in product
and customer mix. The Hematology Division gross margin percentage decrease of
1% in fiscal 2004 was due to changes in customer mix.

Selling, general and administrative expenses increased $2.8 million (12.7%) and
$2.3 million (12.1%) in fiscal 2005 and 2004, respectively. Selling, general
and administrative expenses were as follows (in thousands):

                            =======       =======      =======

R&D System's selling, general and administrative expenses increased $1.9
and $1.1 million in fiscal 2005 and 2004, respectively. The increase in fiscal
2005 was the result of increased profit sharing and stock bonus expense of
$742,000, increased Biotechnology Division personnel costs related to annual
wage increases and additional sales and marketing personnel of $326,000 and
increased advertising, promotion and web-site design consulting of $152,000.
The increase in fiscal 2004 from fiscal 2003 was mainly the result of increased
profit sharing and stock bonus expense of $902,000.

R&D Europe's selling, general and administrative expenses increased
$672,000 (9%) and $839,000 (13%) in fiscal 2005 and 2004, respectively. The
majority of the increases were the result of the exchange rates to convert
expenses from British pounds to U.S. dollars. In British pounds, R&D Europe's
selling, general and administrative expenses increased 3% for both fiscal 2005
and 2004.

Corporate selling, general and administrative expenses increased $212,000
and $383,000 in fiscal 2005 and 2004, respectively. The increase in fiscal 2005
was the result of higher audit and accounting related fees. The increase in
fiscal 2004 was largely the result of increased consulting fees incurred
associated with compliance with Sarbanes-Oxley ($173,000), higher audit and
accounting related fees ($78,000) and higher directors' and officers' liability
insurance premiums ($100,000).

                                     18


Research and development expenses decreased $2.4 million in fiscal 2005 after
increasing $192,000 in fiscal 2004. Included in research and development
expenses in fiscal 2003 and 2004 are the Company's share of losses in equity
method investments.

Research and development expenses are composed of the following (in thousands):

In May 2004, the Company changed from the equity method to the cost method
of accounting for its investment in CCX and no longer records its share of CCX
losses in its consolidated results. The change to the cost method of accounting
for CCX was the result of the Company's ownership percentage declining below
20% and qualitative factors which indicated that the Company does not exercise
significant influence over the operations of CCX. The Company's net investment
in CCX at both June 30, 2005 and 2004 was $5.1 million. As a development stage
company, CCX is dependent on its ability to raise additional funds to continue
its research and development efforts. If such funding were unavailable or
inadequate to fund operations, the Company would potentially recognize an
impairment loss to the extent of its remaining net investment.

During the fourth quarter of fiscal 2004, the Company determined that its
investment in DGI was other than temporarily impaired and wrote off the
remaining net investment of $1.5 million as an impairment loss.

Beginning in fiscal 2005, the Company's share of Hemerus losses are
included in other non-operating expenses since Hemerus began selling product
and was no longer considered a development stage company.

Excluding CCX, DGI and Hemerus losses, research and development expenses
by the Company increased $459,000 and $527,000 in fiscal 2005 and 2004,
respectively. These increases were primarily the result of the development of
new cytokines, antibodies and assay kits by R&D Systems' Biotechnology
Division.

Other non-operating expense (income) consists of foreign currency transaction
gains, rental income, building expenses related to properties not used in
operations and the Company's fiscal 2005 share of equity in losses by Hemerus

The Company's net investment in Hemerus at June 30, 2005 and 2004 was $2.6
million and $2.9 million, respectively. Hemerus' success is dependent in part,
upon receiving FDA clearance to market its products. If such clearance is not
received, the Company would potentially recognize an impairment loss to the
extent of its remaining net investment.

Income taxes for fiscal 2005, 2004 and 2003 were provided at rates of
approximately 33.8%, 35.9% and 34.7%, respectively. U.S. federal taxes have
been reduced as a result of federal tax-exempt interest income, the federal
benefit of extraterritorial income and the federal and state credits for
research and development expenditures. Foreign income taxes have been provided
at rates which approximate the tax rates in the countries in which R&D Europe
operates. Without significant business developments, the Company expects income
tax rates for fiscal 2006 to be 34% to 35%.

$139 million compared to $177 million at June 30, 2004. At June 30, 2003, cash,
equivalents and available-for-sale investments were $119 million. The Company
has an unsecured line of credit of $750,000 available at June 30, 2005. The
line of credit expires on October 31, 2005. The interest rate on the line of
credit is at the prime rate (6.25% at June 30, 2005). There were no borrowings
on the line in the current or prior fiscal year.

Management of the Company expects to be able to meet its foreseeable
future cash and working capital requirements for operations, debt repayment,
facility expansion and capital additions through currently available funds,
cash generated from operations and maturities of available-for-sale
investments.

Cash flows from operating activities. The Company generated cash from
operations of $74.4 million, $65.6 million and $55.2 million in fiscal 2005,
2004 and 2003, respectively. The increase in cash generated from operating
activities in fiscal 2005 of $8.8 million was the result of a net earnings
increase of $13.2 million partially offset by a smaller increase in income
taxes payable. Excluding the losses by equity method investments and the
impairment loss in fiscal 2004, which do not affect cash balances, net earnings
in fiscal 2005 increased $8.8 million from fiscal 2004. For the year ended June
30, 2005, income taxes payable increased $307,000 compared to $3.3 million for
the year ended June 30, 2004. The difference was mainly the result of increased
tax payments made in fiscal 2005.

The increase in cash generated from operating activities in fiscal 2004 of
$10.3 million was the result of increased net earnings and a smaller decrease
in trade and other accounts payable compared to fiscal 2003. These changes were
partially offset by a smaller increase in income taxes payable in fiscal 2004
compared to fiscal 2003. Net earnings in fiscal 2004 increased $9.1 million
before the $1.5 million impairment loss, which did not affect the Company's
cash balances. A $6.1 million decrease in trade and other accounts payable in
fiscal 2003 was mainly the result of $3.8 million less in royalties payable to
Genzyme, Inc. stemming from the fiscal 1999 acquisition of Genzyme's research
product business under which royalties were due through fiscal 2003. The $3.1
million change in income taxes payable between fiscal 2003 and fiscal 2004 was
due to higher U.S. taxable income in fiscal 2004 ($4.0 million increase in
income taxes payable compared to fiscal 2003) offset by higher U.S. income tax
payments in fiscal 2004 ($7.5 million more than made in fiscal 2003).

Cash flows from investing activities. Capital additions consist of the

On January 3, 2005, the Company acquired property adjacent to its
Minneapolis facility for $10.4 million. Two million of the purchase price had
been deposited in escrow in fiscal 2002. The renovation and construction costs
in fiscal 2005, 2004 and 2003 were for renovation of Minneapolis property
purchased in fiscal 2002, construction connecting the purchased property to R&D
Systems' existing property and construction of a parking ramp. The Company
acquired property in southeast Minnesota in fiscal 2003 and, in fiscal 2004 and
2005 constructed additional facilities at this site to house goats used in the
production of its antibodies. The land and building purchases and construction
were all financed through cash on hand, cash generated from operations and
maturities of short-term available-for-sale investments. Costs to finish
construction in Minneapolis are estimated at $8 million and are expected to be
completed in mid-fiscal 2006. All construction is expected to be financed
through currently available funds and cash generated from operating activities.

Capital additions for laboratory, manufacturing and computer equipment
planned for fiscal 2006 are expected to be approximately $2.2 million and are
expected to be financed through currently available cash and cash generated
from operations.

The Company's net purchases of (proceeds from) available-for-sale
investments in fiscal 2005, 2004 and 2003 was ($65.1) million, $47.3 million,
and $6.5 million, respectively. The Company's investment policy is to place
excess cash in municipal and corporate bonds with the objective of obtaining
the highest possible return with the lowest risk, while keeping funds
accessible.


                                       20


In fiscal 2004, the Company purchased a 10% interest in Hemerus Medical,
LLC (Hemerus) for $3 million. Hemerus was formed in March 2001 and has acquired
and is developing technology for the separation of leukocytes from blood and
blood components. The Company accounts for its investment in Hemerus under the
equity method of accounting. The Company's net investment in Hemerus, was $2.6
and $2.9 million at June 30, 2005 and 2004, respectively.

In fiscal 2004, the Company made additional investments totaling $5.1
million in ChemoCentryx, Inc. (CCX), a technology and drug development company.
After the additional investments, the Company holds a 19.9% equity interest in
CCX and accounts for the investment under the cost method of accounting as
discussed previously. The Company's net investment in CCX was $5.1 million at
both June 30, 2005 and 2004.

Subsequent to June 30, 2005, the Company, through its R&D Systems
subsidiary, acquired Fortron Bio Science, Inc. and BiosPacific, Inc. All of the
shares of privately-held Fortron and substantially all of the assets of
privately-held BiosPacific were acquired for an aggregate $20.0 million in
cash. R&D Systems also assumed certain liabilities of BiosPacific, and incurred
transaction expenses. The transactions were financed through cash and cash
equivalents on hand at June 30, 2005.

Cash flows from financing activities. The Company received $1.4 million for the
exercise of warrants to purchase 120,000 shares of common stock in fiscal 2005.
The Company received $6.6 million, $4.1 million and $2.4 million for the
exercise of options for 252,000, 241,000 and 265,000 shares of common stock in
fiscal 2005, 2004 and 2003, respectively.

In fiscal 2003, the Company purchased 50,000 shares of common stock for
its employee Stock Bonus Plans for $1.1 million. The shares were issued to the
Company's Stock Bonus Plans to settle the fiscal 2002 accrued liability balance
of $296,000 (12,587 shares) and the fiscal 2003 accrued liability balance of
$457,000 (20,002 shares). The remaining 17,411 shares were issued to the
Company's Stock Bonus Plans in fiscal 2005 at fair market value of $704,000.
These shares along with 6,410 shares purchased in fiscal 2005 for $260,000 were
issued to settle the fiscal 2004 accrued liability balance of $964,000.

In March 2005, the Company repurchased approximately 2.9 million shares of
its common stock under an accelerated stock buyback ("ASB") transaction for an
initial value of approximately $100 million ($34.45 per share). The effect of
the reduction in oustanding shares on earnings per diluted share was $0.04 in
fiscal 2005. The repurchase of the shares was funded with a portion of the
Company's cash and available-for-sale investments. The ASB agreement is subject
to a market price adjustment provision based upon a volume weighted average
price during the nine-month period ending in December 2005. In December 2005,
the Company will, at its option, settle the ASB agreement in cash or shares of
the Company's common stock. At an average market price of $43.50, which
approximates the average market price from the transaction date through June
30, 2005, the settlement amount for the contract would be approximately $18.6
million or about 428,000 shares.

In fiscal 2003, the Company purchased and retired 1,027,000 shares of
Company common stock at a market value of $22.5 million. In May 1995, the
Company announced a plan to purchase and retire its common stock. Since May
1995, in addition to the ASB transaction previously discussed, the Board of
Directors has authorized the purchase of $40 million of common stock. Through
June 30, 2005, $33 million of common stock had been purchased under the plan.

The Company has never paid cash dividends and currently has no plans to do
so in fiscal 2006.


CONTRACTUAL OBLIGATIONS

The following table summarizes the Company's contractual obligations and
commercial commitments as of June 30, 2005 (in thousands):

OFF-BALANCE SHEET ARRANGEMENTS

The Company is not a party to any off-balance sheet transactions, arrangements
or obligations other than the ASB agreement discussed previously, that have, or
are reasonably likely to have, a material effect on the Company's financial
condition, changes in the financial condition, revenues or expenses, results of
operations, liquidity, capital expenditures or capital resources.


CRITICAL ACCOUNTING POLICIES

Management's discussion and analysis of the Company's financial condition and
results of operations are based upon the Company's consolidated financial
statements, which have been prepared in accordance with accounting principles
generally accepted in the United States of America. The preparation of these
financial statements requires management to make estimates and judgments that
affect the reported amounts of assets, liabilities, revenues and expenses, and
related disclosure of contingent assets and liabilities. On an ongoing basis,
management evaluates its estimates. Management bases its estimates on
historical experience and on various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

The Company has identified the policies outlined below as critical to its
business operations and an understanding of results of operations. The listing
is not intended to be a comprehensive list of all accounting policies.

Valuation of accounts receivable. The Company performs ongoing credit
evaluations of its customers and adjusts credit limits based upon payment
history and the customers' current creditworthiness, as determined by
management's review of their current credit information. The Company
continuously monitors collections and payments from its customers and maintains
a provision for estimated credit losses based upon the Company's historical
experience and any specific customer collection issues that have been
identified. While such credit losses have historically been within the
Company's established provisions, if the financial condition of the Company's
customers were to deteriorate, resulting in an impairment of their ability to
make payments, additional allowances may be required. Gross trade receivables
totaled $22.2 million and the allowance for doubtful accounts was $118,000 at
June 30, 2005.

Valuation of inventory. Inventories are stated at the lower of cost (first-in,
first-out method) or market. The Company regularly reviews inventory on hand
for slow-moving and obsolete inventory, inventory not meeting quality control
standards and inventory subject to expiration. The manufacturing process for
proteins and antibodies has and may continue to produce quantities in excess of
forecasted usage. The Company values its manufactured protein and antibody
inventory based on a two-year forecast. Proteins and antibody quantities in
excess of the two-year usage forecast are considered impaired and not included
in the inventory value. The value of protein and antibody inventory does not
change significantly from quarter to quarter. Protein and antibody production
is generally for high-volume products or for new products with limited initial
sales. The Company capitalizes protein and antibody costs each period in
inventory, however given the insignificant changes in these inventory balances
each quarter, substantially all manufacturing costs for proteins and
antibodies, consisting largely of wages, benefits, facility and equipment
costs, are expensed each quarter. A change in inventory value as a result of
estimate changes in the two-year forecast is reflected in cost of sales in the
period of change. Manufacturing costs and changes in inventory value for
proteins and antibodies charged to cost of sales were $6.6 million in fiscal
2005. Inventories of proteins and antibodies in excess of the two-year usage
forecast were $10.2 million at June 30, 2005.

Valuation of goodwill. The Company is required to perform an annual review for
impairment of goodwill in accordance with Statement of Financial Accounting
Standards No. 142, GOODWILL AND OTHER INTANGIBLE ASSETS. Goodwill is considered
to be impaired if it is determined that the carrying value of the reporting
unit exceeds its fair value. Assessing the impairment of goodwill requires the
Company to make judgments regarding the fair value of the net assets of its
reporting units and the allocation of the carrying value of shared assets to
the reporting units. The Company's annual assessment included comparison of the
carrying value of the net assets of the Biotechnology Division to its share of
the Company's market capitalization at June 30, 2005. A significant change in
the Company's market capitalization or in the carrying value of net assets of
the Biotechnology Division could result in an impairment charge in future
periods. Goodwill at June 30, 2005 was $12.5 million.

                                       22


Valuation of intangible and other long-lived assets. The Company periodically
assesses the impairment of intangible and other long-lived assets which
requires it to make assumptions and judgments regarding the fair value of these
asset groups. Asset groups are considered to be impaired if their carrying
value exceeds the asset groups' ability to continue to generate income from
operations and positive cash flow in future periods. If asset groups are
considered impaired, the amount by which the carrying value exceeds its fair
value would be written off as an impairment loss. Intangible assets and other
long-lived assets at June 30, 2005, were $1.6 million and $617,000,
respectively.

Valuation of investments. The Company has made equity investments in several
start-up and early development stage companies, among them CCX, DGI and
Hemerus. The accounting treatment of each investment (cost method or equity
method) is dependent upon a number of factors, including, but not limited to,
the Company's share in the equity of the investee and the Company's ability to
exercise significant influence over the operating and financial policies of the
investee. In determining which accounting treatment to apply, the Company must
make judgments based upon the quantitative and qualitative aspects of the
investment.

The Company periodically assesses its equity investments for impairment.
Development stage companies, of the type the Company has invested in, are
dependent on their ability to raise additional funds to continue research and
development efforts and on receiving patent protection and/or FDA clearance to
market their products. If such funding were unavailable or inadequate to fund
operations or if patent protection or FDA clearance were not received, the
Company would potentially recognize an impairment loss to the extent of its
remaining net investment. The Company's net investments at June 30, 2005 in CCX
and Hemerus were $5.1 million and $2.6 million, respectively. During the fourth
quarter of fiscal 2004, the Company determined that its investment in DGI was
other than temporarily impaired and wrote off the remaining net investment of
$1.5 million.

Income taxes. The Company operates within multiple taxing jurisdictions and is
subject to audit in these jurisdictions. These audits can involve complex
issues, which may require an extended period of time to resolve. In fiscal
2005, the Company reached a settlement with the State of Minnesota for $525,000
for fiscal years 2000 to 2002. The settlement was fully accrued for at June 30,
2004.

Assessment of claims or pending litigation. The Company is routinely subject to
claims and involved in legal actions which are incidental to the business of
the Company. Although it is difficult to predict the ultimate outcome of these
matters, management believes that any ultimate liability will not materially
affect the consolidated financial position or results of operations of the
Company. As additional information becomes available, the Company will assess
the potential liabilities related to claims or pending litigation and revise
estimates as needed. Such revisions could materially impact the Company's
consolidated financial position or results of operations.


RECENT ACCOUNTING PRONOUNCEMENTS

In December 2004, the Financial Accounting Standards Board (FASB) issued
Statement of Accounting Standards No. 123 (Revised 2004) (SFAS No. 123R),
SHARE-BASED PAYMENT. SFAS No. 123R is a revision of FASB Statement No. 123,
ACCOUNTING FOR STOCK-BASED COMPENSATION and supersedes Accounting Principles
Board (APB) Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES and its
related implementation guidance. The Statement focuses primarily on accounting
for transactions in which an entity obtains employee services through
share-based payment transactions. SFAS No 123R requires a public entity measure
the cost of employee services received in exchange for the award of equity
instruments based on the fair value of the award at the date of grant. The cost
will be recognized over the period during which an employee is required to
provide services in exchange for the award. SFAS No. 123R is effective as of
the beginning of the first annual reporting period that begins after June 15,
2005 and the Company will adopt the standard in the first quarter of fiscal
2006. While the Company cannot precisely determine the impact on net earnings
as a result of the adoption of SFAS No 123R, estimated compensation expense
of about $1.2 million or $0.03 per diluted share is anticipated for fiscal
2006. The ultimate amount of increased compensation expense will be dependent
on the number of future option shares granted, their timing and vesting period
and the method used to calculated the fair value of the awards, among other
factors.

                                       23


In November 2004, the FASB issued SFAS No. 151, INVENTORY COSTS. The
Statement amends Accounting Research Bulletin No. 43 to clarify the accounting
for abnormal amounts of idle facility expense, freight, handling costs and
spoilage. The Statement also requires the allocation of fixed production
overheads to inventory be based on normal production capacity. SFAS No. 151 is
effective for the Company for inventory costs incurred beginning in fiscal
2006. Adoption of the Statement is not expected to have a significant impact on
the Company's consolidated financial statements.

In December 2004, the FASB issued Staff Position No. 109-1, APPLICATION OF
FASB STATEMENT NO. 109 (SFAS 109), ACCOUNTING FOR INCOME TAXES, TO THE TAX
DEDUCTION ON QUALIFIED PRODUCTION ACTIVITIES PROVIDED BY THE AMERICAN JOBS
CREATION ACT OF 2004 (FSP 109-1). FSP 109-1 clarifies that the manufacturer's
deduction provided for under the American Jobs Creation Act of 2004 (AJCA)
should be accounted for as a special deduction in accordance with SFAS 109 and
not as a tax rate reduction. The adoption of FSP 109-1 had no impact on the
Company's results of operations or financial position for fiscal year 2005
because the manufacturer's deduction is not available to the Company until
fiscal year 2006. The Company is evaluating the effect that the manufacturer's
deduction will have in subsequent years.

The FASB also issued Staff Position No. 109-2, ACCOUNTING AND DISCLOSURE
GUIDANCE FOR THE FOREIGN EARNINGS REPATRIATION PROVISION WITHIN THE AMERICAN
JOBS CREATION ACT OF 2004 (FSP 109-2). The AJCA introduces a special one-time
dividends received deduction on the repatriation of certain foreign earnings to
a U.S. taxpayer provided certain criteria are met. The Company periodically
evaluates the possibility of repatriating foreign earnings. At the present
time, deferred taxes have not been recorded on undistributed earnings of
foreign subsidiaries as it is the Company's intent to indefinitely reinvest the
undistributed earnings.

In May 2005, the FASB issued SFAS No. 154, ACCOUNTING CHANGES AND ERROR
CORRECTIONS. The Statement replaces APB Opinion No. 20, ACCOUNTING CHANGES and
SFAS No. 3, REPORTING ACCOUNTING CHANGES IN INTERIM FINANCIAL STATEMENTS. SFAS
No. 154 requires companies to apply voluntary changes in accounting principles
retrospectively whenever practicable. The requirements are effective for the
Company beginning in fiscal 2007. Adoption of the Statement is not expected to
have a significant impact on the Company's consolidated financial statements.


MARKET RISK

At the end of fiscal 2005, the Company had an independently managed investment
portfolio of fixed income securities, excluding those classified as cash and
cash equivalents, of $58.7 million (see Note A of Notes to Consolidated
Financial Statements). These securities, like all fixed income instruments, are
subject to interest rate risk and will decline in value if market interest
rates increase.

The Company operates internationally, and thus is subject to potentially
adverse movements in foreign currency rate changes. The Company is exposed to
market risk from foreign exchange rate fluctuations of the euro and the British
pound to the U.S. dollar as the financial position and operating results of the
Company's U.K. subsidiary and European operations are translated into U.S.
dollars for consolidation. At the current level of R&D Europe operating
results, a 10% increase or decrease in the average exchange rate used to
translate operating results into U.S. dollars would have an approximate $1.4
million effect on consolidated operating income annually. Month-end exchange
rates between the British pound and the U.S. dollar were as follows:

                                           YEAR ENDED JUNE 30,
                                  2005          2004         2003
                                --------      --------     --------
High                             $1.92         $1.87         $1.66
Low                               1.79          1.58          1.55
Average                           1.86          1.75          1.59

                                       24


The Company's exposure to foreign exchange rate fluctuations also arises
from transferring funds from the U.K. subsidiary to the U.S. subsidiary and
from transferring funds from the German subsidiary and French sales office to
the U.K. subsidiary. At June 30, 2005 and 2004, the Company had $642,000 and
$119,000 dollar denominated intercompany debt at its U.K. subsidiary and the
U.K. subsidiary had $510,000 and $93,000 dollar denominated intercompany debt
from its European operations. These intercompany balances are revolving in
nature and are not deemed to be long-term balances. The Company's U.K.
subsidiary recognized net foreign currency gains of 135,000 British pounds
($251,000), 36,000 British pounds($64,000) and 224,000 British pounds
($356,000) for the years ended June 30, 2005, 2004 and 2003, respectively.
The Company's German subsidiary recognized net foreign currency losses of
125,000 euros ($157,000) for the year ended June 30, 2005. The Company does
not enter into foreign exchange forward contracts to reduce its exposure to
foreign currency rate changes on intercompany foreign currency denominated
balance sheet positions.

As of June 30, 2005, the Company's long-term debt consisted of a mortgage
note payable. The interest rate on the mortgage is at a floating interest rate
at the one month London interbank offered rate (Libor) plus 2.5% with a floor
of 4%. The floating interest rate on the mortgage note payable was 5.6% as of
June 30, 2005.

In March 2005, the Company repurchased approximately 2.9 million shares of
its common stock under an accelerated stock buyback ("ASB") transaction for an
initial value of approximately $100 million ($34.45 per share). The ASB
agreement is subject to a market price adjustment provision based upon a volume
weighted average price during the nine-month period ending in December 2005. In
December 2005, the Company will, at its option, settle the ASB agreement in
cash or shares of the Company's common stock. At an average market price of
$43.50, which approximates the average market price from the transaction date
through June 30, 2005, the settlement amount for the contract would be
approximately $18.6 million or about 428,000 shares.

Approximately 1.8 million of the shares repurchased are subject to a
collar, which effectively sets a minimum and maximum price the Company will be
obligated to pay for such shares. The collar was established in exchange for an
up-front payment of $3.5 million. The minimum and maximum price for the 1.8
million shares is approximately $39.00 and $41.00, respectively. The maximum
additional amount that could be required to be paid related to the shares
subject to the collar is $8.5 million or about 215,000 shares. The adjusted
price of the remaining 1.1 million repurchased shares will be based upon the
difference between the volume weighted average price during the nine-month
period and the initial $34.45 per share payment. For each $1.00 change in the
average market price during the nine-month period, the Company's obligation
under the uncollared portion of the agreement would increase or decrease by
$1.1 million. Should the Company elect to settle the ASB agreement in shares,
each $1.00 increase in the average market price over $40.00 during the
nine-month period will increase the number of shares required for settlement
under the uncollared portion of the agreement, but reduce the number of shares
required by the collared portion of the contract by a net amount of about
15,000 shares.


FORWARD-LOOKING INFORMATION

Statements in this Annual Report, and elsewhere, that are forward-looking
involve risks and uncertainties which may affect the Company's actual results
of operations. Certain of these risks and uncertainties which have affected
and, in the future, could affect the Company's actual results are discussed
below.

The Company's biotechnology products are sold primarily to research
scientists at pharmaceutical and biotechnology companies and at university and
government research institutions. Changes in spending on research by such
companies and in funding of such universities and institutions by government,
including the National Institutes of Health, affects the revenues and earnings
of the Company. The Company carries essentially no backlog of orders and
changes in the level of orders received and filled daily can cause fluctuations
in quarterly revenues and earnings.

Approximately one quarter of the Company's sales are made through its
European subsidiary, R&D Systems Europe, which makes its sales in foreign
currencies. The Company's revenues and earnings are, therefore, affected by
fluctuations in currency exchange rates.

The biotechnology industry is subject to rapid and significant
technological change. While the hematology controls industry historically has
been less subject to rapid change, it too is evolving and is impacted
significantly by changes in the automated testing equipment offered by
instrument manufacturers. Competitors of the Company are numerous and include,
among others, specialized biotechnology firms, medical laboratory instrument
and equipment manufacturers and disposables suppliers, major pharmaceutical
companies, universities and other research institutions. There can be no
assurance that the Company's competitors will not succeed in developing
technologies and products that are more effective than any which have been
or are being developed by the Company or that would render the Company's
technologies and products obsolete or noncompetitive.


                                       25


The Company's success will depend, in part, on its ability to obtain
licenses and patents, maintain trade secret protection and operate without
infringing the proprietary rights of others. The Company has obtained and is
negotiating licenses to produce a number of cytokines and related products
claimed to be owned by others. Since the Company has not conducted a patent
infringement study for each of its products, it is possible that products of
the Company may unintentionally infringe patents of third parties or that the
Company may have to alter its products or processes, pay licensing fees or
cease certain activities because of patent rights of third parties, thereby
causing additional unexpected costs and delays which may have a material
adverse effect on the Company.

The Company's expansion strategies, which include internal development of
new products, collaborations, investments in joint ventures and companies
developing new products related to the Company's business, and the acquisition
of companies for new products and additional customer base, carry risks that
objectives will not be achieved and future earnings will be adversely affected.
Under the equity method of accounting, a percentage of the losses of certain
companies in which the Company invests will be reported as losses of the
Company. The Company may not have control of the expense levels of such
companies and their losses may be greater than those anticipated by the
Company. Additionally, if the Company determines that its investment in such
companies is "other than temporarily" impaired, the Company may write off its
entire investment in such company.

Ongoing research and development activities and the production and
marketing of certain of the Company's products are subject to regulation by
numerous governmental authorities in the United States and other countries. The
approval process applicable to clinical diagnostic products of the type that
may be developed by the Company may take a year or more. Delays in obtaining
approvals could adversely affect the marketing of new products developed by the
Company.

Recruiting and retaining qualified scientific and production personnel to
perform research and development work and product manufacturing are critical to
the Company's success. The Company's anticipated growth and its expected
expansion into areas and activities requiring additional expertise will require
the addition of new personnel and the development of additional expertise by
existing personnel. The failure to attract and retain such personnel could
adversely affect the Company's business.

The Company undertakes no obligation to update or revise any
forward-looking statements made due to new information or future events.
Investors are cautioned not to place undue emphasis on these statements.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        TECHNE CORPORATION AND SUBSIDIARIES

                    Years Ended June 30, 2005, 2004 and 2003

A. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

DESCRIPTION OF BUSINESS: TECHNE Corporation and Subsidiaries (the Company) are
engaged domestically in the development and manufacture of biotechnology
products and hematology calibrators and controls. These activities are
primarily conducted through its wholly-owned subsidiary, Research and
Diagnostic (R&D) Systems, Inc. Through its wholly-owned U.K. subsidiary, R&D
Systems Europe Ltd., the Company distributes biotechnology products throughout
Europe. R&D Systems Europe Ltd. has a sales subsidiary, R&D Systems GmbH, in
Germany and a sales office in France.

ESTIMATES: The preparation of consolidated financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosures of contingent assets and
liabilities at the date of the consolidated financial statements and the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

RISK AND UNCERTAINTIES: There are no concentrations of business transacted with
a particular customer or supplier nor concentrations of revenue from a
particular product or geographic area that would severely impact the Company in
the near term.

PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include the
accounts of the Company and its wholly-owned subsidiaries. All material
intercompany accounts and transactions have been eliminated.

TRANSLATION OF FOREIGN FINANCIAL STATEMENTS: Assets and liabilities of the
Company's foreign operations are translated at year-end rates of exchange and
the foreign statements of earnings are translated at the average rate of
exchange for the year. Gains and losses resulting from translating foreign
currency financial statements are not included in operations but are
accumulated in other comprehensive income. Foreign currency transaction gains
and losses are included in operations.

REVENUE RECOGNITION: The Company recognizes revenue when persuasive evidence of
an arrangement exists, delivery has occurred or services have been rendered,
the price is fixed or determinable and collectibility is reasonably assured.
Payment terms for shipments to end-users are net 30 days. Payment terms for
distributor shipments may range from 30 to 90 days. Products are shipped FOB
shipping point. Freight charges billed to end-users are included in net sales
and freight costs are included in cost of sales. Freight charges on shipments
to distributors are paid directly by the distributor. Any claims for credit or
return of goods must be made within 10 days of receipt. Revenues are reduced to
reflect estimated credits and returns.

RESEARCH AND DEVELOPMENT: Research and development expenditures are expensed as
incurred. Development activities generally relate to creating new products,
improving or creating variations of existing products, or modifying existing
products to meet new applications. Included in research and development expense
for fiscal 2004 and 2003 were the Company's share of losses by development
stage companies in which it had invested due to the Company obtaining research
market rights to products developed by the investee companies. (See Investments
below).

ADVERTISING COSTS: Advertising expenses (including production and communication
costs) for fiscal 2005, 2004 and 2003 were $2.6 million, $2.6 million and $2.5
million, respectively. The Company expenses advertising expenses as incurred.

INCOME TAXES: The Company uses the asset and liability method of accounting for
income taxes. Deferred tax assets and liabilities are recognized to record the
income tax effect of temporary differences between the tax basis and financial
reporting basis of assets and liabilities. Deferred tax assets and liabilities
are measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

                                       31


CASH AND EQUIVALENTS: Cash and cash equivalents include cash on hand and
highly-liquid investments with original maturities of three months or less.

AVAILABLE-FOR-SALE INVESTMENTS: Available-for-sale investments consist of debt
instruments with original maturities of generally greater than three months to
three years. The Company considers all of its marketable securities
available-for-sale and reports them at fair market value. Fair market values
are based on quoted market prices. Unrealized gains and losses on
available-for-sale securities are excluded from income, but are included in
other comprehensive income. If an "other than temporary" impairment is
determined to exist, the difference between the value of the investment
security recorded in the financial statements and the Company's current
estimate of the fair value is recognized as a charge to earnings in the period
in which the impairment is determined.

At June 30, 2005 and 2004, the amortized cost and market value of the Company's
available-for-sale securities by major security type were as follows (in
thousands):

Contractual maturities of available-for-sale securities are shown below (in
thousands). Expected maturities may differ from contractual maturities because
borrowers may have the right to recall or prepay obligations with or without
call or prepayment penalties.


YEAR ENDING JUNE 30:
- --------------------
Due within one year           $16,790
Due in one to three years      41,871
                              -------
                              $58,661
                              =======

Proceeds from maturities or sales of available-for-sale securities were $212.0
million, $96.9 million and $58.0 million during fiscal 2005, 2004 and 2003,
respectively. There were no material gross realized gains or losses on these
sales. Realized gains and losses are determined on the specific identification
method.

INVENTORIES: Inventories are stated at the lower of cost (first-in, first-out
method) or market. The Company regularly reviews inventory on hand for
slow-moving and obsolete inventory, inventory not meeting quality control
standards and inventory subject to expiration. The manufacturing process for
proteins and antibodies has and may continue to produce quantities in excess of
forecasted usage. The Company values its manufactured protein and antibody
inventory based on a two-year forecast. Proteins and antibody quantities in
excess of the two-year usage forecast are considered impaired and not included
in the inventory value. The value of protein and antibody inventory does not
change significantly from quarter to quarter. Protein and antibody production
is generally for high-volume products or for new products with limited initial
sales. The Company capitalizes protein and antibody costs each period in
inventory, however given the insignificant changes in these inventory balances
each quarter, substantially all manufacturing costs for proteins and
antibodies, consisting largely of wages, benefits, facility and equipment
costs, are expensed each quarter. A change in inventory value as a result of
changes in the two-year forecast is reflected in cost of sales in the period of
change. Manufacturing costs and changes in inventory value for proteins and
antibodies charged to cost of sales were $6.6 million, $6.4 million and $6.7
million for the fiscal years ended June 30, 2005, 2004 and 2003, respectively.

DEPRECIATION AND AMORTIZATION: Equipment is depreciated using the straight-line
method over an estimated useful life of five years. Buildings, building
improvements and leasehold improvements are amortized over estimated useful
lives of five to forty years.

                                       32


GOODWILL AND INTANGIBLE ASSETS: At June 30, 2005 the Company had net
unamortized goodwill of $12.5 million. The Company completed its annual
impairment testing of goodwill and concluded that no impairment existed as of
June 30, 2005. The Company used discounted cash flow and other fair value
methodologies to assess impairment. Other intangible assets are being amortized
over their estimated useful lives. (See Note D.)

IMPAIRMENT OF INTANGIBLE AND OTHER LONG-LIVED ASSETS: Management reviews the
carrying value of intangible and other long-lived assets for impairment
whenever events or changes in circumstances indicate the carrying amount of an
asset may not be recoverable. Recoverability of assets is based on the
estimated future cash flows expected to result from the use of these assets.
Should the sum of the expected future net cash flows be less than the carrying
value, an impairment loss would be recognized. An impairment loss would be
measured by the amount by which the carrying value of the asset group exceeds
the fair value of the asset group based on discounted estimated future cash
flows. To date, management has determined that no impairment exists.

INVESTMENTS: The Company has invested in the Preferred Stock (Series A and B)
of ChemoCentryx, Inc. (CCX), a technology and drug development company. Through
April 2004 the Company held 26% of the outstanding stock of CCX and accounted
for the investment under the equity method of accounting. In May and June, 2004
CCX obtained $38.1 million in financing through the issuance of approximately
14.7 million shares of Preferred (Series B) Stock. The financing included a
$5.1 million investment by the Company. After the financing the Company held a
19.9% equity interest in CCX. The Company evaluated the cost versus equity
method of accounting for its investment in CCX and determined that it does not
have the ability to exercise significant influence over the operating and
financial policies of CCX and therefore, after April 2004, accounted for its
investment on a cost basis. The Company's net investment in CCX was $5.1 at
June 30, 2005 and 2004. In connection with its original investment in CCX, the
Company was issued warrants for 1.7 million shares of CCX Preferred Stock
(Series A) which expire on December 31, 2005.

On August 2, 2001, the Company made an equity investment of $3 million in
Discovery Genomics, Inc. (DGI) Series A Preferred Stock. DGI holds licenses
from the University of Minnesota to develop technologies used for functional
genomics and the discovery of drug targets. The Company holds a 38% equity
interest in DGI and accounted for this investment under the equity method of
accounting. During the fourth quarter of fiscal 2004, the Company determined
that its investment in DGI was other than temporarily impaired and wrote off
the remaining net investment of $1.5 million. The Company has been issued
warrants for 1.5 million shares of DGI Preferred Stock (Series A) which expire
on August 2, 2008.

On January 1, 2004, the Company purchased a 10% interest in Hemerus Medical,
LLC (Hemerus) for $3 million. Hemerus was formed in March 2001 and has acquired
and is developing technology for the separation of leukocytes from blood and
blood components. Leukoreduced blood is important in blood transfusion. Hemerus
owns two patents and has several patent applications pending and is currently
pursuing FDA clearance to market its products in the U.S. In parallel with this
investment, R&D Systems entered into a Joint Research Agreement with Hemerus.
The research will involve joint projects to explore the use of Hemerus's filter
technology to applications within R&D Systems' Hematology and Biotechnology
Divisions. Such applications, if any, may have commercial potential in other
laboratory environments. The Company accounts for its investment in Hemerus
under the equity method of accounting as Hemerus is a limited liability
corporation. The Company's net investment in Hemerus was $2.6 million and $2.9
million at June 30, 2005 and 2004, respectively.

The Company does not provide loans, guarantees or other financial assistance to
CCX, DGI or Hemerus and has no obligation to provide additional funding.

STOCK OPTIONS: As permitted through June 30, 2005 by Statement of Financial
Accounting Standards (SFAS) No. 123, the Company has elected to continue
following the guidance of Accounting Principles Board (APB) Opinion No. 25 for
measurement and recognition of stock-based transactions with employees. No
compensation cost has been recognized for stock options granted to employees
under the plans because the exercise price of all options granted was at least
equal to the fair value of the common stock at the date of grant. In December
2004, the Financial Accounting Standards Board issued Statement of Accounting
Standards No. 123 (Revised 2004) (SFAS No. 123R), SHARE-BASED PAYMENT. The
Statement requires the recognition of compensation cost for equity instruments
issued to employees based on the fair value at the date of grant. SFAS No. 123R
is effective as of the beginning of the first annual reporting period that
begins after June 15, 2005 and the Company will adopt the standard in the first
quarter of fiscal 2006.

If compensation cost for employee options granted under the Company's stock
option plans had been determined based on the fair value at the grant dates,
consistent with the methods provided in SFAS No. 123, ACCOUNTING FOR
STOCK-BASED COMPENSATION, the Company's net earnings and earnings per share

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES: The Company has determined that
it has no free-standing or embedded derivatives. All contracts that contain
provisions meeting the definition of a derivative also meet the requirements
of, and have been designated as, normal purchases or sales. The Company's
policy is to not use free-standing derivatives and to not enter into contracts
with terms that cannot be designated as normal purchases or sales.

RECENT ACCOUNTING PRONOUNCEMENTS: In December 2004, the Financial Accounting
Standards Board (FASB) issued Statement of Accounting Standards No. 123
(Revised 2004) (SFAS No. 123R), SHARE-BASED PAYMENT. SFAS No. 123R is a
revision of FASB Statement No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION and
supersedes Accounting Principles Board (APB) Opinion No. 25, ACCOUNTING FOR
STOCK ISSUED TO EMPLOYEES and its related implementation guidance. The
Statement focuses primarily on accounting for transactions in which an entity
obtains employee services through share-based payment transactions. SFAS No
123R requires a public entity measure the cost of employee services received in
exchange for the award of equity instruments based on the fair value of the
award at the date of grant. The cost will be recognized over the period during
which an employee is required to provide services in exchange for the award.
SFAS No. 123R is effective as of the beginning of the first annual reporting
period that begins after June 15, 2005 and the Company will adopt the standard
in the first quarter of fiscal 2006. While the Company cannot precisely
determine the impact on net earnings as a result of the adoption of SFAS No
123R, estimated compensation expense of about $1.2 million or $0.03 per diluted
share is anticipated for fiscal 2006. The ultimate amount of increased
compensation expense will be dependent on the number of option shares granted
during the year, their timing and vesting period and the method used to
calculated the fair value of the awards, among other factors.

In November 2004, the FASB issued SFAS No. 151, INVENTORY COSTS. The Statement
amends Accounting Research Bulletin No. 43 to clarify the accounting for
abnormal amounts of idle facility expense, freight, handling costs and
spoilage. The Statement also requires the allocation of fixed production
overheads to inventory be based on normal production capacity. SFAS No. 151 is
effective for the Company for inventory costs incurred beginning in fiscal
2006. Adoption of the Statement is not expected to have a significant impact on
the Company's consolidated financial statements.

In December 2004, the FASB issued Staff Position No. 109-1, APPLICATION OF FASB
STATEMENT NO. 109 (SFAS 109), ACCOUNTING FOR INCOME TAXES, TO THE TAX DEDUCTION
ON QUALIFIED PRODUCTION ACTIVITIES PROVIDED BY THE AMERICAN JOBS CREATION ACT
OF 2004 (FSP 109-1). FSP 109-1 clarifies that the manufacturer's deduction
provided for under the American Jobs Creation Act of 2004 (AJCA) should be
accounted for as a special deduction in accordance with SFAS 109 and not as a
tax rate reduction. The adoption of FSP 109-1 had no impact on the Company's
results of operations or financial position for fiscal year 2005 because the
manufacturer's deduction is not available to the Company until fiscal year
2006. The Company is evaluating the effect that the manufacturer's deduction
will have in subsequent years.

The FASB also issued Staff Position No. 109-2, ACCOUNTING AND DISCLOSURE
GUIDANCE FOR THE FOREIGN EARNINGS REPATRIATION PROVISION WITHIN THE AMERICAN
JOBS CREATION ACT OF 2004 (FSP 109-2). The AJCA introduces a special one-time
dividends received deduction on the repatriation of certain foreign earnings to
a U.S. taxpayer provided certain criteria are met. The Company periodically
evaluates the possibility of repatriating foreign earnings. At the present
time, deferred taxes have not been recorded on undistributed earnings of
foreign subsidiaries as the amounts are considered permanently invested. If the
Company decides to repatriate foreign earnings a one-time charge may be
recorded for the deferred taxes.

In May 2005, the FASB issued SFAS No. 154, ACCOUNTING CHANGES AND ERROR
CORRECTIONS. The Statement replaces APB Opinion No. 20, ACCOUNTING CHANGES and
SFAS No. 3, REPORTING ACCOUNTING CHANGES IN INTERIM FINANCIAL STATEMENTS. SFAS
No. 154 requires companies to apply voluntary changes in accounting principles
retrospectively whenever practicable. The requirements are effective for the
Company beginning in fiscal 2007. Adoption of the Statement is not expected to
have a significant impact on the Company's consolidated financial statements.

RECLASSIFICATIONS: Certain reclassifications have been made to prior years

These reclassifications had no impact on net earnings or stockholders' equity

granting of stock options to employees (the TECHNE Corporation 1997 and 1987
Incentive Stock Option Plans) and to employees, officers, directors and
consultants (the TECHNE Corporation 1998 and 1988 Nonqualified Stock Option
Plans). The plans are administered by the Board of Directors, or a committee
designated by the Board, which determines the persons who are to receive awards
under the plans, the number of shares subject to each award and the term and
exercise price of each option. The maximum term of options granted under all
plans is ten years. The number of shares of common stock authorized to be
issued and available for grant at June 30, 2005 are as follows (in thousands):

WARRANTS: In fiscal 2000, the Company issued warrants to purchase 120,000
shares of the Company's common stock at $11.89 per share as a nonrefundable
deposit on an option to purchase property adjacent to its R&D Systems'
facility. The fair market value of the warrants at issuance was $0.9 million.
On October 28, 2004, the warrants were exercised for $1.4 million.

STOCK REPURCHASE: In March 2005, the Company repurchased approximately 2.9
million shares of its common stock under an accelerated stock buyback ("ASB")
transaction for an initial value of approximately $100 million ($34.45 per
share). The transaction was completed under a privately negotiated contract
with an investment bank. The investment bank borrowed the 2.9 million shares to
complete the transaction and will purchase the replacement shares in the open
market over a nine-month period beginning in March 2005. The ASB agreement is
subject to a market price adjustment provision based upon a volume weighted
average price during the nine-month period ending in December 2005. In December
2005, the Company will, at its option, settle the ASB agreement in cash or
shares of the Company's common stock. At an average market price of $43.50,
which approximates the average market price from the transaction date through
June 30, 2005, the settlement amount for the contract would be approximately
$18.6 million or about 428,000 shares. The contract was classified as equity
and the purchase price adjustment will be reflected in stockholders equity at
the time of settlement.

Approximately 1.8 million of the shares repurchased are subject to a collar,
which effectively sets a minimum and maximum price the Company will be
obligated to pay for such shares. The collar was established in exchange for an
up-front payment of $3.5 million. The minimum and maximum price for the 1.8
million shares is approximately $39.00 and $41.00, respectively. The maximum
additional amount that could be required to be paid related to the shares
subject to the collar is $8.5 million or about 215,000 shares. The adjusted
price of the remaining 1.1 million repurchased shares will be based upon the
difference between the volume weighted average price during the nine-month
period and the initial $34.45 per share payment. For each $1.00 change in the
average market price during the nine-month period, the Company's obligation
under the uncollared portion of the agreement would increase or decrease by
$1.1 million. Should the Company elect to settle the ASB agreement in shares,
each $1.00 increase in the average market price over $40.00 during the
nine-month period will increase the number of shares required for settlement
under the uncollared portion of the agreement, but reduce the number of shares
required by the collared portion of the contract by a net amount of about
15,000 shares.

A deferred tax valuation allowance is required when it is more likely than not
that all or a portion of deferred tax assets will not be realized. The Company
has provided a valuation allowance for the potential capital loss carryover
resulting from the excess tax basis in equity investment and on the foreign tax
credit carryforward. The Company believes that it is more likely than not that
the recorded deferred tax asset, net of valuation allowance, will be realized.

Undistributed earnings of the Company's foreign subsidiaries amounted to
approximately $51.8 million as of June 30, 2005. Deferred taxes have not been
provided on such undistributed earnings, as it is the Company's intent to
indefinitely reinvest the undistributed earnings in the foreign operations.

The Company's tax returns are subject to audit by various governmental entities
in the normal course of business. The Company had received an audit assessment
of $1.75 million, plus interest, from the State of Minnesota for fiscal years
2000 to 2002. The Company appealed the assessment and in October 2004, reached
a settlement with the State of Minnesota for $525,000, plus interest of
$81,000. The settlement amount of $525,000 was fully accrued for at June 30,
2004.

N. SUBSEQUENT EVENT:

On July 1, 2005, the Company, through its R&D Systems subsidiary, acquired
Fortron Bio Science, Inc., a developer and manufacturer of monoclonal and
polyclonal antibodies, antigens and other biological reagents. R&D Systems
simultaneously acquired BiosPacific, Inc., a worldwide supplier of biologics to
manufacturers of in vitro diagnostic systems (IVDs) and immunodiagnostic kits.
BiosPacific is the primary distribution arm of Fortron. Fortron and BiosPacific
had shared a unique strategic relationship since 1992 that combined Fortron's
development and manufacturing excellence with BiosPacific's marketing and sales
expertise. Fortron and BiosPacific generated combined revenues of approximately
$8.7 million in calendar 2004. The acquisitions will enhance R&D Systems'
ability to serve the diagnostics industry.

All of the shares of privately-held Fortron and substantially all of the assets
of privately-held BiosPacific were acquired for an aggregate $20.0 million in
cash. R&D Systems also assumed certain liabilities of BiosPacific, and incurred
transaction expenses. The acquisition will be accounted for under the purchase
method.



          REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders TECHNE Corporation
Minneapolis, Minnesota

We have audited the accompanying consolidated balance sheets of TECHNE
Corporation and Subsidiaries (the Company) as of June 30, 2005 and 2004, and
the related consolidated statements of earnings, stockholders' equity and
comprehensive income, and cash flows for each of the years in the three-year
period ended June 30, 2005. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of TECHNE Corporation
and Subsidiaries as of June 30, 2005 and 2004, and the results of their
operations and their cash flows for each of the years in the three-year period
ended June 30, 2005, in conformity with U.S. generally accepted accounting
principles.

We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the effectiveness of TECHNE
Corporation's internal control over financial reporting as of June 30, 2005,
based on criteria established in Internal Control--Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO),
and our report dated September 12, 2005 expressed an unqualified opinion on
management's assessment of, and the effective operation of, internal control
over financial reporting.

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, the Company conducted an
evaluation, under the supervision and with the participation of the principal
executive officer and principal financial officer, of the Company's
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-
15(e) under the Securities Exchange Act of 1934 (the "Exchange Act")).  Based
on this evaluation, the principal executive officer and principal financial
officer concluded that the Company's disclosure controls and procedures are
effective to ensure that information required to be disclosed by the Company
in reports that it files or submits under the Exchange Act is recorded,
processed, summarized and reported within the time periods specified in
Securities and Exchange Commission rules and forms.

Changes in Internal Controls

There was no change in the Company's internal control over financial
reporting during the Company's most recently completed fiscal quarter that
has materially affected, or is reasonably likely to materially affect, the
Company's internal control over financial reporting.

Management's Annual Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and maintaining
adequate internal control over financial reporting, as such term is defined
in Exchange Act Rule 13a-15(f). As of June 30, 2005, management, under the
supervision of the chief executive officer and chief financial officer,
assessed the effectiveness of the Company's internal control over financial
reporting based on the criteria for effective internal control over financial
reporting established in "Internal Control - Integrated Framework," issued by
the Committee of Sponsoring Organizations (COSO) of the Treadway Commission.
Based on the assessment, management determined that the Company maintained
effective internal control over financial reporting as of June 30, 2005.

KPMG LLP, the independent registered public accounting firm that audited the
consolidated financial statements of the Company included in this Annual
Report on Form 10-K, has issued an attestation report on management's
assessment of the effectiveness of the Company's internal control over
financial reporting as of June 30, 2005. The report, which expresses
unqualified opinions on management's assessment and on the effectiveness of
the Company's internal control over financial reporting as of June 30, 2005,
follows.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders
TECHNE Corporation

We have audited management's assessment, included in the accompanying report
entitled "Management's Annual Report on Internal Control Over Financial
Reporting", that TECHNE Corporation and subsidiaries  (the Company)
maintained effective internal control over financial reporting as of June 30,
2005, based on criteria established in Internal Control-Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO).  TECHNE Corporation's management is responsible for
maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting.
Our responsibility is to express an opinion on management's assessment and an
opinion on the effectiveness of the Company's internal control over financial
reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether
effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal
control over financial reporting, evaluating management's assessment, testing
and evaluating the design and operating effectiveness of internal control,
and performing such other procedures as we considered necessary in the
circumstances.  We believe that our audit provides a reasonable basis for our
opinion.

A company's internal control over financial reporting is a process designed
to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes
in accordance with generally accepted accounting principles. A company's
internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of
the assets of the company;  (2) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and
that receipts and expenditures of the company are being made only in
accordance with authorizations of management and directors of the company;
and (3) provide reasonable assurance regarding prevention or timely detection
of  unauthorized  acquisition,  use, or  disposition  of the company's assets
that could have a material effect on the financial statements.

                                    44


Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements.  Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may deteriorate.

In our opinion, management's assessment that TECHNE Corporation and
subsidiaries maintained effective internal control over financial reporting
as of June 30, 2005, is fairly stated, in all material respects, based on
criteria established in Internal Control-Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO).
Also, in our opinion, TECHNE Corporation and subsidiaries maintained, in all
material respects, effective internal control over financial reporting as of
June 30, 2005, based on criteria established in Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO).

We also have audited, in accordance with the standards of the Public Company
Accounting Oversight Board (United States), the consolidated balance sheets
of TECHNE Corporation and subsidiaries as of June 30, 2005 and 2004, and the
related consolidated statements of earnings, stockholders' equity and
comprehensive income, and cash flows for each of the years in the three-year
period ended June 30, 2005, and our report dated September 12, 2005 expressed
an unqualified opinion on those consolidated financial statements.

Board of Directors and Stockholders
TECHNE Corporation
Minneapolis, Minnesota

Under the date of September 12, 2005, we reported on the consolidated balance
sheets of TECHNE Corporation and Subsidiaries as of June 30, 2005 and 2004
and the related consolidated statements of earnings, stockholders' equity and
comprehensive income, and cash flows for each of the years in the three-year
period ended June 30, 2005 in the annual report on Form 10-K for fiscal 2005.
In connection with our audit of the aforementioned financial statements, we
also have audited the related financial statement schedule in the annual
report on Form 10-K for fiscal 2005 as listed in the accompanying index. This
financial statement schedule is the responsibility of the Company's
management. Our responsibility is to express an opinion on the financial
statement schedule based on our audits.

In our opinion, such financial statement schedule, when considered in
relation to the basic financial statements taken as a whole, presents fairly,
in all material respects, the information set forth therein.
