TECHNE CORPORATION RELEASES UNAUDITED THIRD QUARTER
                       RESULTS FOR FISCAL YEAR 2007

Minneapolis/May 1, 2007/--Techne Corporation's (NASDAQ: TECH) consolidated
net earnings for the quarter ended March 31, 2007 increased 17.4% to $23.9
million or $0.60 per diluted share compared to $20.3 million and $0.52 per
diluted share for the quarter ended March 31, 2006.  For the nine months
ended March 31, 2007, Techne's consolidated net earnings increased 15.5% to
$62.2 million or $1.57 per diluted share compared with $53.9 million or $1.36
per diluted share for the nine months ended March 31, 2006.  The improvement
in results was mainly due to increased consolidated net sales and improved
gross margin percentages.

Consolidated net sales for the quarter and nine months ended March 31, 2007
were $60.2 million and $165.1 million, respectively. This was an increase of
9.8% and 9.6% from the quarter and nine months ended March 31, 2006.

Biotechnology net sales, which includes sales by R&D Systems' Biotechnology
Division, Fortron and BiosPacific, for the quarter and nine months ended
March 31, 2007 were $39.1 million and $108.5 million, increases of 6.9% and
8.4%, respectively, from the same prior-year periods. Approximately $1.2
million of the increase in Biotechnology net sales during the first six
months of fiscal 2007 was the result of price increases made in January 2006.

R&D Europe's net sales for the quarter and nine months ended March 31, 2007
were $17.4 million and $45.6 million, increases of 20.1% and 15.5%,
respectively, from the same prior-year periods.  In British pound sterling,
R&D Europe's net sales increased 7.2% and 4.9% for the quarter and nine
months ended March 31, 2007. Hematology net sales of $3.7 million for the
quarter and $11.0 million for the nine months ended March 31, 2007 were
essentially flat from the same prior-year periods.

Consolidated gross margins were 80.0% and 79.4% for the quarter and nine
months ended March 31, 2007, respectively, compared to 77.9% and 77.5% for
the quarter and nine months ended March 31, 2006. Biotechnology gross margins
increased to 80.4% and 80.3% for the quarter and nine months ended March 31,
2007 from 78.8% and 78.2% for the same prior-year periods mainly as a result
of changes in product mix. Biotechnology gross margins were also positively
affected by the sale of inventory acquired from Fortron and BiosPacific in
fiscal 2006, which was valued at fair market under purchase accounting.
Included in cost of sales for the quarter and nine months ended March 31,
2007 were $100,000 and $455,000, respectively, related to the sale of
acquired inventory compared to $397,000 and $1.3 million, respectively, for
the same prior-year periods.

The income tax rate of 35.2% for the quarter ended March 31, 2007 increased
from 33.9% for the first and second quarter of fiscal 2007 as a result of
changes in state apportionment estimates. Income tax rates are expected to
range from approximately 33.5% to 34.5% in the fourth quarter of fiscal 2007.

Consolidated net earnings and diluted earnings per share for the quarter and
nine months ended March 31, 2007 were favorably impacted by the change in
exchange rates from the prior year used to convert R&D Europe results from
British pound sterling to U.S. dollars.  The change in exchange rates from
the prior year increased consolidated net earnings approximately $600,000 and
$1.3 million for the quarter and nine months ended March 31, 2007,
respectively.
