TECHNE CORPORATION
                   RELEASES UNAUDITED SECOND QUARTER RESULTS
                               FOR FISCAL YEAR 2008

Minneapolis/January 29, 2008/--Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended December 31, 2007 increased
26.7% to $23.6 million or $.60 per diluted share compared with $18.7 million
or $.47 per diluted share for the quarter ended December 31, 2006.  For the
six months ended December 31, 2007, Techne's consolidated net earnings
increased 22.0% to $46.7 million or $1.18 per diluted share compared with
$38.3 million or $0.97 per diluted share for the six months ended December
31, 2006.

Net earnings as a percentage of net sales improved to 38.9% for the six
months ended December 30, 2007 from 36.5% in the first six months of last
year. The improvement in net earnings was mainly due to increased
consolidated net sales. The favorable 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 $339,000 ($.01 per diluted share) for the quarter
and $742,000 ($.02 per diluted share) for the six months ended December 31,
2007.

Consolidated net sales for the quarter and six months ended December 31, 2007
were $62.1 million and $120.1 million, respectively. This was an increase of
18.4% and 14.6% from the quarter and six months ended December 31, 2006,
respectively. Consolidated net sales 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
16.5% and 12.6% for the quarter ended and six months ended December 31, 2007,
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 $39.1 million and $78.0
million, for the quarter and six months ended December 31, 2007, increases of
17.1% and 12.5%, respectively.  This improvement was primarily the result of
increased volume and the timing of shipments to diagnostic customers.  The
timing of diagnostic customer sales is not predictable and these sales
increases are not necessarily indicative of future sales.  Excluding the
increased sales to diagnostic customers, Biotechnology net sales increased
12.9% and 12.3% for the quarter ended and six months ended December 31, 2007,
respectively, from the comparable prior year periods.

R&D Europe's net sales for the quarter and six months ended December 31, 2007
were $19.0 million and $34.5 million, increases of 24.7% and 22.3%,
respectively, from the same prior-year periods.  In British pounds, R&D
Europe's net sales increased 18.5% and 14.8% for the quarter and six months
ended December 31, 2007. Hematology net sales for the quarter and six months
ended December 31, 2007 were $4.0 million and $7.6 million, increases of 3.8%
and 4.1%, respectively, compared to the quarter and six months ended December
31, 2006.

Tom Oland, President and Chief Executive Officer of Techne Corporation, said
"Second quarter sales exceeded our expectations in all segments of our
business and in nearly all product lines and geographical territories.
However, given the exceptionally strong sales growth rate in this quarter and
due to the Easter holiday falling in March 2008, we caution our shareholders
not to expect a similar sales growth rate in our third fiscal quarter."

Mr. Oland added, "Our business is doing well.  We continue to release new
products and build for our future.  For fiscal 2008, given current trends for
our specific products, we continue to target revenue growth in the range of
8% to 11%."

Consolidated gross margins were 79.5% and 79.3% for the quarter and six
months ended December 31, 2007 respectively, compared to 79.6% and 79.1% for
the quarter and six months ended December 31, 2006. Biotechnology gross
margins decreased to 79.4% and 79.8% for the quarter and six months ended
December 31, 2007 from 80.8% and 80.2% for the same prior-year periods mainly
as a result of higher volume sales to diagnostic customers. The decrease in
Biotechnology gross margins was partially offset by higher margins in Europe
due to favorable exchange rates and changes in sales mix as a result of
higher sales growth in the Biotechnology Division as compared to the sales
growth in the lower margin Hematology Division.

Selling, general and administrative expenses for the quarter and six months
ended December 31, 2007 increased $1.8 million (20.6%) and $2.8 million
(17.9%), respectively. These increases primarily resulted because of wage and
salary increases and the hiring of additional marketing and administrative
personnel to support the Company's sales growth. The second quarter increase
also resulted from increased professional fees of $340,000, increased stock
option expense of $352,000, additional profit sharing of $331,000, R&D China
selling, general and administrative expenses of $144,000, and the change in
foreign currency exchange rates used to convert British pounds to U.S.
dollars of $116,000.  Second quarter selling, general and administrative
expenses increased approximately $2.5 million from the first quarter of
fiscal 2008 due primarily because of costs associated with production and
printing of the annual catalogs and the annual granting of stock options to
the Company's Board of Directors (approximately $1.2 million).

Selling, general and administrative expenses for the six months ended
December 31, 2007 also increased because of increased professional fees of
$386,000, increased stock option expense of $357,000, additional profit
sharing of $536,000, R&D China selling, general and administrative expenses
of $244,000 and the change in foreign currency exchange rates used to convert
British pounds to U.S. dollars of $283,000.

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.

The effective tax rate was 33.6% for the quarter and six months ended
December 31, 2007 as compared to 33.9% for the quarter and six months ended
December 31, 2006.  Without significant business developments, the Company
expects its fiscal 2008 effective income tax rate to range from approximately
33.5% to 34.5%.

The Company repurchased approximately 321,000 shares of its common stock
during the second quarter of fiscal 2008 for approximately $20.6 million.
