TECHNE CORPORATION RELEASES UNAUDITED SECOND QUARTER
                   RESULTS FOR FISCAL YEAR 2007

Minneapolis/January 30, 2007/--Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended December 31, 2006 increased
13.0% to $18.7 million or $0.47 per diluted share compared to $16.5 million
and $0.42 per diluted share for the quarter ended December 31, 2005.  For the
six months ended December 31, 2006, Techne's consolidated net earnings
increased 14.3% to $38.3 million or $0.97 per diluted share compared with
$33.5 million or $0.84 per diluted share for the six months ended December
31, 2005.  The improvement in results was mainly due to increased
consolidated net sales and improved gross margin percentages.

Consolidated net sales for the quarter and six months ended December 31, 2006
were $52.5 million and $104.9 million, respectively. This was an increase of
9.3% and 9.5% from the quarter and six months ended December 31, 2005.

Biotechnology net sales, which includes sales by R&D Systems' Biotechnology
Division, Fortron and BiosPacific, for the quarter and six months ended
December 31, 2006 were $33.4 million and $69.3 million, increases of 7.3% and
9.3%, respectively, from the same prior-year periods.  Net sales for the
Biotechnology Division increased 11.1% and 10.9% for the quarter and six
months ended December 31, 2006, respectively, mainly as a result of increased
volume from the same prior-year periods. Approximately $500,000 and $1.2
million of the increase in Biotechnology Division net sales for the quarter
and six months ended December 31, 2006, respectively, was the result of price
increases.  BiosPacific net sales increased for the quarter ended September
30, 2006 from the first quarter of the prior year, but decreased from the
prior year for the quarter ended December 31, 2006 due to the timing of large
shipments to diagnostic customers.

R&D Europe's net sales for the quarter and six months ended December 31, 2006
were $15.3 million and $28.2 million, increases of 16.4% and 12.8%,
respectively, from the same prior-year periods.  In British pound sterling,
R&D Europe's net sales increased 4.3% and 3.5% for the quarter and six months
ended December 31, 2006. Hematology net sales for the quarter and six months
ended December 31, 2006 were $3.8 million and $7.3 million, increases of 1.2%
and 0.2%, respectively, compared to the quarter and six months ended December
31, 2005.

Consolidated gross margins were 79.6% and 79.1% for the quarter and six
months ended December 31, 2006, respectively, compared to 77.7% and 77.2% for
the quarter and six months ended December 31, 2005. Biotechnology gross
margins increased to 80.8% and 80.2% for the quarter and six months ended
December 31, 2006 from 78.4% and 77.9% for the same prior-year periods mainly
as a result of changes in product mix. Biotechnology gross margins were also
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 six months ended December 31,
2006 were $64,000 and $355,000, respectively, related to the sale of acquired
inventory compared to $281,000 and $856,000, respectively, for the same prior
year periods.

Consolidated net earnings and diluted earnings per share for the quarter and
six months ended December 31, 2006 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 $466,000 and
$672,000 for the quarter and six months ended December 31, 2006,
respectively.

In October 2006, the Company repaid its mortgage debt. The total payment of
$13.8 million included the mortgage principal balance, accrued interest and a
5% prepayment penalty of $651,000. The prepayment penalty and $78,000 of
unamortized loan origination fees were included in interest expense for the
quarter ended December 31, 2006.
