TECHNE CORPORATION RELEASES UNAUDITED FIRST QUARTER
                       RESULTS FOR FISCAL YEAR 2009

Minneapolis/October 22, 2008/--Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended September 30, 2008 increased
23.9% to $28.6 million or $.74 per diluted share compared with $23.1 million
or $.58 per diluted share for the quarter ended September 30, 2007. Net
earnings as a percentage of net sales improved from 39.8% in the first
quarter of last year to 41.2% for the quarter ended September 30, 2008. The
improvement in net earnings was mainly due to increased consolidated net
sales. The unfavorable impact on consolidated net earnings of the change in
exchange rates used to convert foreign currencies (primarily British pound
sterling and Euros) to U.S. dollars was $310,000 ($.01 per diluted share) for
the quarter ended September 30, 2008.

Consolidated net sales for the quarter ended September 30, 2008 were $69.3
million, an increase of 19.6% from the same prior-year quarter. Consolidated
net sales were favorably affected by the strength of foreign currencies as
compared to the U.S. dollar. Excluding the effect of changes in foreign
currency exchange rates, consolidated net sales increased 18.4% for the
quarter ended September 30, 2008 from the quarter ended September 30, 2007.
The quarter ended September 30, 2008 included one more selling day than the
comparable prior-year quarter.

Biotechnology net sales, which include sales by R&D Systems' Biotechnology
Division, R&D Systems China and BiosPacific, for the quarter ended September
30, 2008, were $46.1 million, an increase of 18.7% from the same prior-year
quarter. R&D Europe's net sales for the quarter were $18.9 million, an
increase of 22.6% from the same prior-year quarter. R&D Europe's net sales
increased 18.4% for the quarter when measured at currency rates in effect in
the comparable prior periods.  Hematology net sales for the quarter were $4.2
million, an increase of 16.1%.  The timing of shipments to OEM customers
positively impacted Hematology sales results during the quarter ended
September 30, 2008 and will likely reduce the Hematology sales growth rate in
the quarter ending December 31, 2008 as compared to the comparable prior-year
quarter.

Consolidated gross margins were 81.1% and 79.1% in the first quarters of
fiscal 2009 and 2008, respectively. The increase in gross margins was due to
higher sales volume on relatively fixed costs and higher margins in Europe
due to favorable exchange rates.

Selling, general and administrative expenses decreased to 12.8% of
consolidated net sales for the quarter ended September 30, 2008 from 14.0%
for the quarter ended September 30, 2007.  Selling, general and
administrative expenses for the quarter ended September 30, 2008 increased
$750,000 (9.3%) from the same prior-year period due mainly to annual wage and
salary increases and increased legal costs of $276,000.  Research and
development expenses increased $729,000 (14.1%) for the quarter ended
September 30, 2008 mainly as a result of increased personnel costs.

The consolidated effective tax rate was 33.4% and 33.6% for the quarters
ended September 30, 2008 and 2007, respectively. As a result of the recent
renewal of the U.S. research and development credit, income tax expense in
the second quarter of fiscal 2008 will include a credit for the January to
June 2008 period in addition to a credit for the current-year six month
period.  Including the increased research and development credit and without
other 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' common stock.  The
Company repurchased approximately 214,000 shares of its common stock during
the first quarter of fiscal 2009 for approximately $15.6 million.  Subsequent
to September 30, 2008, the Company has repurchased an additional 335,000
shares for approximately $22.7 million.  In total, the Company has
repurchased approximately 1.3 million shares of its common stock for
approximately $90.8 million under this authorization.
