TECHNE CORPORATION RELEASES UNAUDITED FIRST QUARTER
                    RESULTS FOR FISCAL YEAR 2008

Minneapolis/October 24, 2007/--Techne Corporation's (NASDAQ: TECH)
consolidated net earnings for the quarter ended September 30, 2007
increased 17.5% to $23.1 million or $.58 per diluted share compared with
$19.6 million or $.50 per diluted share for the quarter ended September
30, 2006. Net earnings as a percentage of net sales improved from 37.5%
in the first quarter of last year to 39.8% for the quarter ended
September 30, 2007. 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 $403,000 ($.01 per
diluted share) for the quarter ended September 30, 2007.

Consolidated net sales for the quarter ended September 30, 2007 were
$58.0 million, an increase of 10.8% from the same prior-year quarter.
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 8.6% for the quarter ended September 30, 2007 from the quarter
ended September 30, 2006.

Biotechnology net sales, which include sales by R&D Systems'
Biotechnology Division, R&D Systems China and BiosPacific, for the
quarter ended September 30, 2007 were $38.9 million, an increase of 8.2%
from the same prior-year quarter. R&D Europe's net sales for the quarter
were $15.4 million, an increase of 19.5% from the same prior-year
quarter. In British pound sterling, R&D Europe's net sales increased
10.7% for the quarter.  Hematology net sales for the quarter were $3.7
million, an increase of 4.4%.

Gross margins were 79.1% and 78.5% in the first quarters of fiscal 2008
and 2007, respectively. The increase in gross margins was due to 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 ended
September 30, 2007 increased $1.0 million (14.5%). The increase resulted
from the change in foreign currency exchange rates used to convert
British pounds to U.S. dollars ($170,000), increased profit sharing of
$205,000 and R&D China selling, general and administrative expenses of
$99,000.  The remainder of the increase was due mainly to annual wage
and salary increases.

The effective tax rate was 33.6% for the quarter ended September 30,
2007 as compared to 33.9% for the quarter ended September 30, 2006.
Without significant business developments, the Company expects its
fiscal 2008 effective income tax rate to range from approximately 33.5%
to 34.5%.
