TECHNE CORPORATION RELEASES UNAUDITED FIRST QUARTER
                        RESULTS FOR FISCAL YEAR 2010

Minneapolis/October 28, 2009/-- Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended September 30, 2009 decreased
6.4% to $26.8 million or $.72 per diluted share compared with $28.6 million
or $.74 per diluted share for the quarter ended September 30, 2008.  The
decline in net earnings was mainly due to foreign currency fluctuations,
decreased consolidated net sales and lower interest income.  Foreign currency
fluctuations and general economic conditions continued to have a negative
impact on consolidated net sales and earnings in the quarter ended September
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 $566,000 ($.01 per diluted share) for the quarter ended September
30, 2009 as compared to the same prior-year period.

Consolidated net sales for the quarter ended September 30, 2009 were $66.5
million, a 4.0% decrease from the quarter ended September 30, 2008.
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 2.2% for
the quarter ended September 30 from the comparable prior-year period.

Biotechnology net sales, which include sales by R&D Systems' Biotechnology
Division, R&D Systems China and BiosPacific, were $44.0 million for the
quarter ended September 30, 2009, a decrease of 4.6% from the quarter ended
September 30, 2008.  The Company attributes the lower sales growth rate to
continued customer caution in a time of economic uncertainty and the
exceptionally strong growth rate of 18.7% in the first quarter of fiscal 2009
as compared to the same quarter in fiscal 2008. North American biotechnology
sales to industrial pharmaceutical and biotechnology customers declined
approximately 12.8% during the first quarter of fiscal 2010 as compared to
the first quarter of fiscal 2009. Biotechnology sales to North American
academic customers and Pacific Rim distributors each grew about 3.9% in the
first quarter of fiscal 2010. Biotechnology sales in China grew 30.1% during
the first quarter of fiscal 2010 compared to the same prior-year period.

R&D Europe's net sales for the quarter ended September 30, 2009 were $17.8
million, a decrease of 5.8% from the same prior-year period.  R&D Europe's
net sales increased 0.8% for the quarter ended September 30, 2009 when
measured at currency rates in effect in the comparable prior period.
Hematology net sales for the quarter ended September 30, 2009 were $4.7
million, an increase of 9.9% compared to the quarter ended September 30,
2008.

Consolidated gross margins were 80.6% for the quarter ended September 30,
2009 compared to 81.1% for the quarter ended September 30, 2008. The decrease
in gross margin percent in the quarter was primarily caused by lower gross
margins in Europe resulting from comparatively unfavorable exchange rates.
The consolidated gross margin percent for the quarter ended September 30,
2009 increased from the quarter ended June 30, 2009 gross margin percentage
of 77.4% as a result of higher gross margins in Europe resulting from
comparatively favorable exchange rates and an improvement in Hematology gross
margins due to higher sales volume.

Selling, general and administrative expenses for the quarter ended September
30, 2009 decreased $802,000 (9.1%) from the quarter ended September 30, 2009.
The decrease in selling, general and administrative expenses from the
comparable prior-year period was the result of lower profit sharing expense
of $635,000 and the effect of the change in exchange rates used to convert
foreign expenses to U.S. dollars of  $198,000.

Interest income decreased $1.7 million for the quarter ended September 30,
2009 from the comparable prior-year period primarily as a result of lower
rates of return on cash and available-for-sale investments.

The effective tax rate for the quarter ended September 30, 2009 was 32.6%
compared to 33.4% for the quarter ended September 30, 2008.  The U.S. credit
for research and development expired at the end of calendar 2007 and was not
renewed until the quarter ended December 31, 2008, resulting in a higher
effective tax rate for the quarter ended September 30, 2008.
