TECHNE CORPORATION RELEASES UNAUDITED FOURTH QUARTER
          RESULTS FOR FISCAL YEAR 2009

Minneapolis/August 4, 2009/-- Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended June 30, 2009
decreased 6.9% to $25.4 million or $.68 per diluted share compared
with $27.3 million or $.70 per diluted share for the quarter ended
June 30, 2008.  For the fiscal year ended June 30, 2009, Techne's
consolidated net earnings increased 1.6% to $105.2 million or $2.78
per diluted share compared with $103.6 million or $2.64 per diluted
share for the fiscal year ended June 30, 2008.  Net earnings as a
percentage of net sales were 39.9% for the fiscal year ended June 30,
2009 as compared to 40.2% in fiscal 2008.

Foreign currency fluctuations and general economic conditions
continued to have a negative impact on consolidated net sales and
earnings in the quarter ended June 30, 2009. The change in exchange
rates used to convert foreign currencies (primarily British pound
sterling and euros) to U.S. dollars reduced net earnings by $1.1
million ($.03 per diluted share) for the quarter and $4.5 million
($.12 per diluted share) for fiscal year 2009, as compared to the same
periods in fiscal 2008.

Consolidated net sales for the quarter and fiscal year ended June 30,
2009 were $64.9 million and $264.0 million, respectively. This was a
4.2% decrease and a 2.5% increase from the quarter and fiscal year
ended June 30, 2008, 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 decreased 0.9% for the
quarter ended June 30, 2009 and increased 5.9% for the fiscal year
ended June 30, 2009, 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 $42.3
million for the quarter ended June 30, 2009, a decrease of 0.6% from
the quarter ended June 30, 2008.  Biotechnology sales were $173.9
million for the fiscal year ended June 30, 2009, an increase of 5.0%
over the same period last year.  North American biotechnology sales to
industrial pharmaceutical and biotechnology customers declined
approximately 2% during the fourth quarter of fiscal 2009.  The
Company attributes the lower fourth quarter sales growth rate to
continued customer caution in a time of economic uncertainty.

R&D Europe's net sales for the quarter and fiscal year ended June 30,
2009 were $18.0 million and $72.5 million, decreases of 14.3% and
4.2%, respectively, from the same prior-year periods.  R&D Europe's
net sales decreased 3.6% for the quarter ended June 30, 2009 and
increased 7.2% for the fiscal year ended June 30, 2009 when measured
at currency rates in effect in the comparable prior periods.   R&D
Europe's net sales for the quarter ended June 30, 2009 were affected
by the timing of the Easter holiday in Europe, which occurred in the
third quarter of fiscal 2008.

Hematology net sales for the quarter and fiscal year ended June 30,
2009 were $4.6 million and $17.5 million, increases of 8.9% and 9.2%,
respectively, compared to the quarter and fiscal year ended June 30,
2008.

Consolidated gross margins were 77.4% and 79.0% for the quarter and
fiscal year ended June 30, 2009, respectively, compared to 79.5% for
both the quarter and fiscal year ended June 30, 2008, respectively.
The decreases in gross margins in the quarter and fiscal year ended
June 30, 2009 were primarily caused by lower gross margins in Europe
resulting from comparatively unfavorable exchange rates. Consolidated
gross margins for the quarter ended June 30, 2009 also decreased from
the quarter ended March 31, 2009 as a result of a change in sales mix
from higher margin Biotechnology Division sales to lower margin
Hematology Division and R&D Europe sales.

Selling, general and administrative expenses for the quarter and
fiscal year ended June 30, 2009 decreased $1.4 million (15.9%) and
$3.6 million (9.7%), respectively from the quarter and fiscal year
ended June 30, 2008. The decrease in selling, general and
administrative expenses from the comparable prior-year periods were
the result of the following (in thousands):

                                          Quarter  Fiscal Year

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

Research and development expenses increased $187,000 (3.2%) and $1.2
million (5.2%), respectively, for the quarter and fiscal year ended
June 30, 2009 from the comparable prior-year periods.

Interest income decreased $1.7 million and $4.6 million for the
quarter and fiscal year ended June 30, 2009, 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 rates for the quarter and fiscal year ended June 30,
2009 were 32.2% and 32.3%, respectively, as compared to effective tax
rates of 32.7% for both of the same prior-year periods.

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.  In April 2009, an additional $60 million was authorized
for repurchase and retirement of common stock. The Company repurchased
approximately 33,000 shares of its common stock during the fourth
quarter of fiscal 2009 for approximately $1.8 million. Approximately
$67.5 million remains available for the repurchase of shares under
these authorizations.
