TECHNE CORPORATION RELEASES UNAUDITED SECOND QUARTER
                    RESULTS FOR FISCAL YEAR 2009

Minneapolis/February 3, 2009/--Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended December 31, 2008 were $23.6
million or $.62 per diluted share compared with $23.6 million or $.60 per
diluted share for the quarter ended December 31, 2007.  For the six months
ended December 31, 2008, Techne's consolidated net earnings increased 11.8%
to $52.2 million or $1.36 per diluted share compared with $46.7 million or
$1.18 per diluted share for the six months ended December 31, 2007.  Net
earnings as a percentage of net sales improved to 39.8% for the six months
ended December 30, 2008 from 38.9% in the first six months of last year.

Foreign currency fluctuations and general economic conditions had a negative
impact on consolidated net sales and earnings in the quarter ended December
31, 2008. The change in exchange rates used to convert foreign currencies
(primarily British pound sterling and Euros) to U.S. dollars reduced net
earnings by $1.5 million ($.04 per diluted share) for the quarter and $1.8
million ($.05 per diluted share) for the six months ended December 31, 2008,
as compared to the same periods in last fiscal year.

Consolidated net sales for the quarter and six months ended December 31, 2008
were $61.9 million and $131.2 million, respectively. This was a 0.4% decrease
and 9.2% increase from the quarter and six months ended December 31, 2007,
respectively. Consolidated net sales were negatively affected by the strength
of the U.S. dollar as compared to foreign currencies. Excluding the effect of
changes in foreign currency exchange rates, consolidated net sales increased
5.0% and 11.5% for the quarter ended and six months ended December 31, 2008,
respectively, from the comparable prior-year periods.

Biotechnology net sales, which include sales by R&D Systems' Biotechnology
Division, R&D Systems China and BiosPacific, were $40.3 million and $86.5
million for the quarter and six months ended December 31, 2008, increases of
3.0% and 10.8%, respectively, from the comparable prior-year periods. North
American biotechnology sales to industrial and academic customers grew at
less than 2% during the second quarter of fiscal 2009.  The Company
attributes the lower second quarter sales growth rate to customer caution in
a time of economic uncertainty.

R&D Europe's net sales for the quarter and six months ended December 31, 2008
were $17.3 million and $36.2 million, a decrease of 9.2% and an increase of
5.1%, respectively, from the same prior-year periods.  R&D Europe's net sales
increased 8.6% for the quarter and 13.0% for the six months ended December
31, 2008 when measured at currency rates in effect in the comparable prior-
year periods.

Hematology net sales for the quarter and six months ended December 31, 2008
were $4.3 million and $8.5 million, increases of 7.2% and 11.5%,
respectively, compared to the quarter and six months ended December 31, 2007.

Consolidated gross margins were 78.3% and 79.8% for the quarter and six
months ended December 31, 2008 respectively, compared to 79.5% and 79.3% for
the quarter and six months ended December 31, 2007. The decrease in gross
margins in the second quarter was primarily caused by lower gross margins in
Europe resulting from unfavorable exchange rates.

Selling, general and administrative expenses for the quarter and six months
ended December 31, 2008 decreased $942,000 (8.9%) and $192,000 (1.0%),
respectively from the quarter and six months ended December 31, 2007. The
decrease in selling, general and administrative expenses from the comparable
prior-year periods were the result of the following (in thousands):

                                              Quarter   Six Months
                                              -------   ----------

  and benefits increases                          413      1,312

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

Second quarter selling, general and administrative expense increased from the
first quarter of fiscal 2009 due primarily to costs associated with
production, printing and mailing of the annual catalog and additional expense
as a result of the annual grant of stock options to the Company's Board of
Directors.

Research and development expenses increased $283,000 (5.1%) and $1.0 million
(9.4%), respectively, for the quarter and six months ended December 31, 2008
from the comparable prior-year periods.

Interest income decreased $1.0 million and $1.2 million for the quarter and
six months ended December 31, 2008, respectively, from the comparable prior-
year periods, primarily as a result of lower rates of return on cash and
available-for-sale investments and to a lesser extent to lower cash and
available-for-sale investment balances.

The effective tax rate was 30.8% for the quarter and 32.3% for the six months
ended December 31, 2008 as compared to 33.6% for the quarter and six months
ended December 31, 2007.  Income tax expense in the second quarter of fiscal
2009 benefited from the renewal of the U.S. research and development credit.
The $695,000 research and development tax credit for the quarter ended
December 31, 2008, included credit for the January to June 2008 period in
addition to a credit for the current year six-month period. Without
significant business developments, the Company expects its fiscal 2009
effective income tax rate to range from approximately 32.5% to 33.5%.

In November 2007, the Company's Board of Directors authorized the repurchase
and retirement of up to $150 million of the Company's common stock.  The
Company repurchased approximately 960,000 shares of its common stock during
the second quarter of fiscal 2009 for approximately $62.7 million.
Approximately $20.0 million remains available for the repurchase of shares
under this authorization.
