TECHNE CORPORATION RELEASES UNAUDITED SECOND QUARTER
                  RESULTS FOR FISCAL YEAR 2006

Minneapolis/January 31, 2006/--Techne Corporation's (NASDAQ: TECH)
consolidated net earnings increased 10.6% to $16.5 million or $.42 per
diluted share for the quarter ended December 31, 2005 compared with $14.9
million or $.36 per diluted share for the quarter ended December 31, 2004.
For the six months ended December 31, 2005, Techne's consolidated net
earnings increased 15.1% to $33.5 million or $.84 per diluted share compared
with $29.1 million or $.70 per diluted share for the six months ended
December 31, 2004.

Consolidated net earnings and diluted earnings per share were negatively
impacted by the decline in exchange rates used to covert R&D Europe results
from British pounds to U.S. dollars and stock option related compensation
expense from the adoption of Financial Accounting Standards Board (FASB)
Statement of Accounting Standards No. 123 (Revised 2004), Share-Based
Payments (SFAS No. 123R). The acquisitions of Fortron Bio Science, Inc. and
BiosPacific, Inc. on July 1, 2005 and an accelerated stock buyback
transaction ("ASB") on March 1, 2005 had positive impacts.  The impact of
these items on comparable earnings and diluted earnings per share is
summarized as follows:

     (1) Net of income taxes

Consolidated net sales for the three and six months ended December 31, 2005
were $48.0 million and $95.7 million, respectively.  This was an increase of
13.7% and 15.1% from the three and six months ended December 31, 2004,
respectively.  R&D Systems' Biotechnology Division net sales for the three
and six months ended December 31, 2005 were $29.0 million and $58.7 million,
increases of 16.5% and 15.6%, respectively.  R&D Europe's net sales for the
three and six months ended December 31, 2005 were $13.1 million and $25.0
million, increases of 1.9% and 4.6%, respectively.  In British pound
sterling, R&D Europe's net sales increased 10.6% and 10.3% for the three and
six months ended December 31, 2005, respectively.  R&D Systems' Hematology
Division net sales for the quarter were $3.8 million, a decrease of 16.3%,
mainly as a result of a large OEM customer changing to a new primary vendor
in January 2005.  Included in net sales for the three and six months ended
December 31, 2005 was $2.2 million and $4.8 million, respectively, of net
sales from Fortron Bio Science, Inc. and BiosPacific, Inc., which were
acquired effective July 1, 2005.

Consolidated gross margins were 77.7% in the second quarter of fiscal 2006 as
compared to 76.7% in the first quarter of fiscal 2006. For the six months
ended December 31, 2005, consolidated gross margins were 77.2%.  Excluding
Fortron and BiosPacific, gross margins were 79.8% compared to 78.8% in the
second quarter of fiscal 2005 and 79.5% compared to the 78.6% in the six
months ended December 31, 2004. This increase was the result of a favorable
mix of higher margin Biotechnology Division sales as compared to Hematology
and R&D Europe sales. Gross margins for Fortron and BiosPacific operations of
34.5% and 35.0% for the quarter and six months ended December 31, 2005,
respectively were negatively affected by purchase accounting related to
inventory acquired.

Selling, general and administrative expenses as a percent of net sales
increased to 16.6% and 15.1% for the three and six month periods ended
December 31, 2005, respectively, primarily because the adoption of SFAS No.
123R related to stock option compensation added $1.1 million of expense for
the three months ended December 31, 2005.  Excluding the impact of adopting
SFAS No. 123R, selling, general and administrative expense as a percent of
net sales decreased to 14.3% from 14.9% for the three months ended December
31, 2005 and 2004, respectively, and to 13.6% from 14.3% in the six month
periods ended December 31, 2005 and 2004, respectively.

Stock compensation expense during the three months ended December 31, 2005
primarily resulted from stock options granted to the Company's non-employee
members of the Board of Directors upon their annual reelection, which
occurred at the Company's October annual meeting, or their initial
appointment.  As a result of adopting SFAS No. 123R, estimated total
compensation expense of approximately $1.7 million or $.04 per diluted share
is anticipated for fiscal 2006 of which approximately $300,000 remains to be
expensed in the last six months of the fiscal year.

The dollar increases in selling, general and administrative expenses were
also impacted by the acquisitions of Fortron and BiosPacifc.

Second quarter expenses are also higher than in the first quarter mainly
because of costs associated with production and printing of the R&D Systems'
2006 catalog.

The Company allocated approximately $12.8 million to goodwill and $7.1
million to other intangible assets arising from the acquisition of Fortron
and BiosPacific. The intangible assets, mainly trade names and customer and
supplier relationships, are being amortized over lives of one to eight years
and amortization expense of $272,000 and $543,000 was recorded for the
quarter and six months ended December 31, 2005, respectively, related to
these assets.

In March 2005, the Company repurchased approximately 2.9 million shares of
its common stock under an ASB for an initial value of approximately $100
million.  The ASB agreement was subject to a market price adjustment
provision that was settled on December 30, 2005 for $26.0 million based on
the volume weighted average price during the nine-month period ended in
December 23, 2005.

Forward Looking Statements:
This earnings release contains forward-looking statements within the meaning
of the Private Litigation Reform Act.  These statements, including our
expectations as to the estimated compensation expense resulting from stock
option expensing, involve risks and uncertainties that may affect the actual
results of operations.  The following important factors, among others, have
affected and, in the future, could affect the Company's actual results: the
integration of the recent acquisitions, the introduction and acceptance of
new biotechnology and hematology products, the levels and particular
directions of research by the Company's customers, the impact of the growing
number of producers of biotechnology research products and related price
competition, the retention of hematology OEM and proficiency survey business,
the impact of currency exchange rate fluctuations, and the costs and results
of research and product development efforts of the Company and of companies
in which the Company has invested or with which it has formed strategic
relationships.  For additional information concerning such factors, see the
Company's annual report on Form 10-K and quarterly reports on Form 10-Q as
filed with the Securities and Exchange Commission.  We undertake no
obligation to update or revise any forward-looking statements we make in this
release due to new information or future events.  Investors are cautioned not
to place undue emphasis on these statements.

Use of Non-GAAP Financial Measures:
The non-GAAP financial measures used in this press release quantify the
impact of adopting Financial Accounting Standards Board (FASB) Statement of
Accounting Standards No. 123 (Revised 2004), Share-Based Payments (SFAS No.
123R) related to the expensing of stock option compensation, the decline in
exchange rates used to covert R&D Europe results from British pounds to U.S.
dollars, the acquisitions of Fortron Bio Science, Inc. and BiosPacific, Inc
on July 1, 2005 and an accelerated stock buyback transaction ("ASB") on March
1, 2005 on reported net sales, selling, general and administrative expenses,
net earnings and earnings per share for the three and six months ended
December 31, 2005 as compared to the reported amounts for the same periods
ended December 31, 2004.  These non-GAAP financial measures are not prepared
in accordance with generally accepted accounting principles and may be
different from non-GAAP financial measures used by other companies.  Non-GAAP
financial measures should not be considered as a substitute for, or superior
to, measures of financial performance prepared in accordance with GAAP.  We
view these non-GAAP financial measures to be helpful in assessing the
Company's ongoing operating results.  In addition, these non-GAAP financial
measures facilitate our internal comparisons to historical operating results
and comparisons to competitors' operating results.  We include these non-GAAP
financial measures in our earnings announcement because we believe they are
useful to investors in allowing for greater transparency related to
supplemental information we use in our financial and operational analysis.
Investors are encouraged to review the reconciliations of the non-GAAP
financial measures used in this press release to their most directly
comparable GAAP financial measures as provided with the financial statements
attached to this press release.
