TECHNE CORPORATION RELEASES UNAUDITED THIRD QUARTER
                  AND NINE MONTH FISCAL YEAR 2013 RESULTS

Minneapolis/April 30, 2013/ Techne Corporation's (NASDAQ:TECH) financial
results for the third quarter and nine months ended March 31, 2013 include
the following highlights:

Third quarter earnings were $33.1 million or $0.90 per diluted share.
Adjusted earnings for the quarter were $32.5 million (a decrease of 3.2%
from the prior fiscal year period) or $0.88 per diluted share.  Earnings
and adjusted earnings were negatively impacted by foreign currency
fluctuations, which reduced reported sales and gross margins.  Adjusted
earnings and adjusted earnings per share exclude intangible asset
amortization and costs recognized upon the sale of inventory that was
written-up to fair value as part of the acquisitions completed in the
quarter ended June 30, 2011 and also exclude certain income tax credits
and changes in income tax estimates.  Adjusted earnings and adjusted
earnings per diluted share for the third quarter of fiscal 2012 also
exclude the impact of impairment charges on certain equity investments and
the reversal of deferred tax asset valuation allowances.

Earnings for the nine-month period ended March 31, 2013 were $84.1 million
or $2.28 per diluted share.  Adjusted earnings for the nine-month period
ended March 31, 2013 were $87.8 million (a decrease of 4.1% from the prior
fiscal year period) or $2.38 per diluted share.  Adjusted earnings and
earnings per diluted share for the nine-month periods were also impacted
by the foreign currency fluctuations and exclude the acquisition-related
items, impairment charges, income tax adjustments and the reversal of
valuation allowance noted above.

Net sales as reported declined 3.2% to $81.0 million for the quarter ended
March 31, 2013. Organic sales declined 3.0% in the quarter.  Organic sales
exclude changes in foreign currency exchange rates.  The third quarter of
fiscal 2013 had one less ship day as compared to the prior fiscal year and
also included the Easter holiday which was in the fourth quarter of the
prior fiscal year.

Net sales as reported declined 2.0% to $231 million for the nine months
ended March 31, 2013.  Organic sales, which exclude changes in foreign
currency exchange rates, declined 0.9% in the nine-month period.  A
stronger U.S. dollar as compared to foreign currencies reduced sales by
$122,000 and $2.6 million in the quarter and nine-month period ended March
31, 2013, respectively, from the comparable prior-year periods.

The Biotechnology segment includes sales made through R&D Systems'
Biotechnology Division, R&D Europe, Tocris, R&D China, BiosPacific and Boston
Biochem.  Biotechnology segment net sales were $75.3 million for the quarter
ended March 31, 2013, a decrease of 3.7% from $78.2 million for the quarter
ended March 31, 2012.  Biotechnology net sales were $214 million for the
nine-month period ended March 31, 2013, a decrease of 2.7% from $220 million
for the nine-month period ended March 31, 2012.  Biotechnology sales declined
3.5% and 1.5% for the quarter and nine month period ended March 31, 2013,
respectively, excluding changes in foreign currency exchange rates.

The table below shows changes to the components of organic sales for the
Biotechnology segment, from the same prior-year periods.

                                Quarter Ended     Nine Months Ended
                                   3/31/13             3/31/13
                                -------------     -----------------
U.S. industrial, pharmaceutical
 and biotechnology                   (2.5%)            (4.2%)
U.S. academic                        (8.5%)            (5.5%)
Europe                              (10.3%)            (2.0%)
China                                24.9%             19.4%
Pacific Rim                           9.6%              4.7%

The Hematology segment includes sales made through R&D Systems' Hematology
Division.  Hematology net sales for the quarter and nine month period ended
March 31, 2013 were $5.7 million and $16.7 million, increases of 4.9% and
7.0%, respectively, from the comparable prior-year periods.

The gross margin percentage was 75.5% in the quarter ended March 31, 2013 as
compared to 75.8% in the comparable prior-year quarter.  For the nine-month
period ended March 31, 2013 the gross margin percentage decreased to 74.4%
from 75.0% in the comparable prior-year period. Gross margins adjusted for
costs recognized upon sale of acquired inventory and amortization of
intangible assets were 77.7% and 79.0% for the quarters ended March 31, 2013
and 2012, respectively, and 76.9% and 78.5% for the nine-month periods ended
March 31, 2013 and 2012, respectively, if such costs were excluded in all
periods.  The decrease in adjusted gross margins for the quarter and nine-
month periods were primarily caused by lower sales volumes and unfavorable
exchange rates.

Selling, general and administrative expenses for the quarter and nine-month
periods ended March 31, 2013 increased $83,000 and declined $57,000 from the
quarter and nine-month period ended March 31, 2012, respectively. Selling,
general and administrative expenses were impacted by decreases in profit
sharing expense of $399,000 and $1.1 million for the quarter and nine-month
periods, respectively, as compared to the prior-year periods.  The increase
in selling, general and administrative expense, excluding profit sharing
impact, was mainly the result of increased marketing wages and consulting
related to upgrading the Company's website.

Research and development expenses for the quarter and nine-month periods
ended March 31, 2013 increased $97,000 (1.4%) and $1.4 million (7.0%) from
the quarter and nine-month periods ended March 31, 2012, respectively.  The
increase in research and development expenses is mainly due to increases in
personnel and supply costs associated with the continuous development and
release of new high-quality biotechnology products.

Other non-operating expenses for the quarter and nine-month periods ended
March 31, 2013 included foreign exchange transaction gains of $289,000 and
$360,000, respectively, compared to foreign exchange transaction gains of
$164,000 and foreign exchange transaction losses of $465,000 for the quarter
and nine-month periods ended March 31, 2012, respectively.

The effective tax rate for the quarter and nine-month periods ended March 31,
2013 were 25.5% and 29.8% as compared to 26.5% and 30.0% for the same prior-
year periods. In January 2013, the U.S. federal credit for research and
development was reinstated retroactively for the period of January 2012
through December 2013.  As a result, in addition to the credit for the
quarter ended March 31, 2013, the Company recorded the credit for calendar
2012 in the third quarter of fiscal 2013.  Also included in third quarter
fiscal 2013 income taxes was a reduction in U.S. tax expense due to changes
in estimates related to foreign source income.  Income taxes for the quarter
and nine-month periods ended March 31, 2012 were positively impacted by $3.0
million due to the reversal of a valuation allowance on deferred tax assets
related to the excess tax basis in the Company's investments in
unconsolidated entities.  Effective tax rates for the remainder of fiscal
2013 are expected to be 30% to 32%.

The Company's investment in ChemoCentryx, Inc. (CCXI) is included in short-
term available for sale investments at March 31, 2013 at a fair-value of
$87.5 million.  The Company's unrealized gain of $58.0 million on the
investment, net of a deferred tax liability of $20.8 million, was included in
accumulated other comprehensive income at March 31, 2013.

The Company did not repurchase any shares of its common stock during the
quarter or nine-month periods ended March 31, 2013.  Approximately $127
million remains available at March 31, 2013 for the repurchase and retirement
of shares under the currently open authorization.

the reported amounts for the same periods ended March 31, 2012:

  - fluctuations in exchange rates used to convert transactions in foreign
currencies (primarily the Euro, British pound sterling and Chinese yuan) to
U.S. dollars;

  - the acquisitions of Boston Biochem, Inc. on April 1, 2011 and Tocris
