TECHNE CORPORATION RELEASES UNAUDITED THIRD QUARTER
                 RESULTS FOR FISCAL YEAR 2009

Minneapolis/April 28, 2009/-- Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended March 31, 2009 decreased 6.6%
to $27.6 million or $.74 per diluted share compared with $29.6 million or
$.76 per diluted share for the quarter ended March 31, 2008.  For the nine
months ended March 31, 2009, Techne's consolidated net earnings increased
4.7% to $79.9 million or $2.10 per diluted share compared with $76.3 million
or $1.94 per diluted share for the nine months ended March 31, 2008.  Net
earnings as a percentage of net sales was 40.1% for the nine months ended
March 31, 2009 as compared to 40.2% in the first nine months of last year.

Foreign currency fluctuations and general economic conditions continued to
have a negative impact on consolidated net sales and earnings in the quarter
ended March 31, 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 $1.5 million ($.04 per diluted share) for the quarter
and $3.3 million ($.09 per diluted share) for the nine months ended March 31,
2009, as compared to the same periods in last fiscal year.

Consolidated net sales for the quarter and nine months ended March 31, 2009
were $67.9 million and $199.1 million, respectively. This was a 2.4% decrease
and a 5.0% increase from the quarter and nine months ended March 31, 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 increased
2.9% and 8.3% for the quarter and nine months ended March 31, 2009,
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 $45.1 million for the
quarter ended March 31, 2009, essentially the same as in the quarter ended
March 31, 2008.  Biotechnology sales were $131.6 million for the nine months
ended March 31, 2009, an increase of 6.9% over the same period last year.
North American biotechnology sales to industrial pharmaceutical and
biotechnology customers declined approximately 5% during the third quarter of
fiscal 2009.  Biotechnology sales to academic and Pacific Rim distributor
customers grew about 3% during the same period.  The Company attributes the
lower third quarter sales growth rate to customer caution in a time of
economic uncertainty.

R&D Europe's net sales for the quarter and nine months ended March 31, 2009
were $18.3 million and $54.5 million, decreases of 9.6% and 0.3%,
respectively, from the same prior-year periods.  R&D Europe's net sales
increased 8.5% and 11.3% for the quarter and nine months ended March 31, 2009
when measured at currency rates in effect in the comparable prior periods.

Hematology net sales for the quarter and nine months ended March 31, 2009
were $4.4 million and $12.9 million, increases of 5.4% and 9.3%,
respectively, compared to the quarter and nine months ended March 31, 2008.

Consolidated gross margins were 78.9% and 79.5% for the quarter and nine
months ended March 31, 2009, respectively, compared to 79.7% and 79.4% for
the quarter and nine months ended March 31, 2008, respectively. The decrease
in gross margins in the third quarter was primarily caused by lower gross
margins in Europe resulting from unfavorable exchange rates.

Selling, general and administrative expenses for the quarter and nine months
ended March 31, 2009 decreased $1.9 million (21.5%) and $2.1 million (7.7%),
respectively from the quarter and nine months ended March 31, 2008. The
decrease in selling, general and administrative expenses from the comparable
prior-year periods were the result of the following (in thousands):

                                                 Quarter  Nine Months
                                                 -------- -----------
Reduction in profit sharing expense              $(1,326)   $(1,943)
Change in exchange rates to convert foreign
  expenses to U.S. dollars                          (651)    (1,538)
Other, including annual wage, salary
  and benefits increases                              44      1,356
                                                 -------    -------
                                                 $(1,933)   $(2,125)
                                                 =======    =======

Research and development expenses decreased $30,000 (0.5%) and increased
$983,000 (5.9%), respectively, for the quarter and nine months ended March
31, 2009 from the comparable prior-year periods.

Interest income decreased $1.6 million and $2.8 million for the quarter and
nine months ended March 31, 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 rate for both the quarter and nine months ended March 31,
2009 was 32.3% as compared to effective tax rates of 31.2% and 32.7%,
respectively, from the same prior-year periods. The effective rate in the
quarter ended March 31, 2008 was positively impacted by changes in state
apportionment estimates. The Company expects its fiscal 2009 effective income
tax rate to range from approximately 32.0% to 33.0%.

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 213,000 shares of its common stock during
the third quarter of fiscal 2009 for approximately $10.5 million.
Approximately $7.5 million remains available for the repurchase of shares
under this authorization.
