TECHNE CORPORATION RELEASES UNAUDITED FOURTH QUARTER
                         RESULTS FOR FISCAL YEAR 2007

Minneapolis/August 7, 2007/--Techne Corporation's (NASDAQ: TECH) consolidated
net earnings for the quarter ended June 30, 2007 increased 17.6% to $22.9
million or $.58 per diluted share compared with $19.5 million or $.49 per
diluted share for the quarter ended June 30, 2006.  Net earnings as a
percentage of net sales improved from 37.4% in the fourth quarter of last
year to 39.2% for the quarter ended June 30, 2007.  For the fiscal year ended
June 30, 2007, Techne's consolidated net earnings increased 16.0% to $85.1
million or $2.15 per diluted share compared with $73.4 million or $1.85 per
diluted share for the fiscal year ended June 30, 2006.  Net earnings as a
percentage of net sales improved from 36.2% last year to 38.1% for fiscal
2007.  The improvement in net earnings was mainly due to increased
consolidated net sales.

Consolidated net sales for the quarter and fiscal year ended June 30, 2007
were $58.4 million and $223.5 million, respectively.  This was an increase of
12.2% and 10.3% from the fourth quarter and fiscal year ended June 30, 2006,
respectively. Fiscal 2007 net sales and earnings were favorably affected by
the strength of the British pound as compared to the U.S. dollar.  Excluding
the effect of changes in foreign currency exchange rates, consolidated net
sales increased 10.1% and 7.7% for the quarter and fiscal year ended June 30,
2007, respectively.

Biotechnology net sales, which include sales by R&D Systems' Biotechnology
Division, Fortron and BiosPacific, for the quarter and fiscal year ended June
30, 2007 were $38.1 million and $146.6 million, increases of 11.0% and 9.1%,
respectively, from the same prior-year periods.  R&D Europe's net sales for
the quarter and fiscal year were $16.2 million and $61.8 million, increases
of 20.1% and 16.6%, respectively, from the same prior-year periods.  In
British pound sterling, R&D Europe's net sales increased 12.0% and 6.6% for
the quarter and fiscal year ended June 30, 2007, respectively.  Hematology
net sales for the quarter and fiscal year were $4.1 million and $15.2
million, decreases of 2.7% and 0.9%, respectively.

Gross margins were 78.3% and 77.3% in the fourth quarter of fiscal 2007 and
2006, respectively, and 79.1% and 77.4% for the fiscal years 2007 and 2006,
respectively.  The improvement in gross margins resulted from lower cost of
goods sold related to inventories acquired from Fortron and BiosPacific that
were valued at fair market value under purchase accounting, higher margins in
Europe due to favorable exchange rates and changes in sales mix as a result
of sales growth in the Biotechnology Division as compared to sales declines
in the lower margin Hematology Division.  Fourth quarter fiscal 2007 margins
declined from the third quarter of fiscal 2007 mainly due to changes in
product mix and valuation estimates in the Biotechnology Division.

Selling, general and administrative expenses for the quarter and fiscal year
ended June 30, 2007 increased $1.6 million (25.1%) and $3.4 million (12.2%),
respectively. The fiscal year expense increase resulted from the change in
foreign currency exchange rates (approximately$750,000) and increases in
personnel and benefit costs, profit sharing and professional fee expenses.
Fourth quarter expenses increased approximately $600,000 from the third
quarter of fiscal 2007 due primarily to the timing of promotional marketing
costs (approximately $300,000) and increased profit sharing costs
(approximately $125,000).

The effective tax rate was 32.9% for the quarter ended June 30, 2007 as
compared to 35.2% for the prior quarter ended March 31, 2007.  The fourth
quarter fiscal 2007 effective tax rate was lower than in the third quarter of
fiscal 2007 due to changes in state apportionment estimates that were made in
the third quarter and a $420,000 reduction  in estimated tax contingency
reserves made in the fourth quarter.  The effective tax rate was 34.0% for
the fiscal years ended both June 30, 2006 and 2007.  Without significant
business developments, the Company expects its fiscal 2008 effective income
tax rate to range from approximately 33.5% to 34.5%.

The impact on consolidated net earnings of the change in exchange rates used
to convert R&D Europe results from British pounds to U.S. dollars was
approximately $368,000 ($.01 per diluted share) and $1.6 million ($.04 per
diluted share) for the quarter and fiscal year ended June 30, 2007,
respectively.
