Re:   Techne Corporation
         Form 10-K for the Year Ended June 30, 2004
         File No. 0-17272

Dear Mr. Rosenberg:

This letter is in response to the comment letter received by us dated October
27, 2004, containing comments to our Form 10-K for the year ended June 30,
2004.  On November 10, 2004, we submitted our response to your comments No.
2-5.  This letter is in response to comment No. 1.

Short-Term Investments, pg.32

1. Comment:

Please provide, supplementally, management's assessment of compliance to
paragraph 17 of SFAS 115 as amended by SFAS 135, given that the Company
currently characterizes debt instruments with maturities of three months to
three years as short-term.

Response:

Our investment portfolio consists of state, municipal and corporate bonds all
of which are considered available-for-sale and all have immediate
marketability. Contractual maturities of the June 30, 2004,  $125.4 million
available-for-sale investments were as follows:  due within one year - $42.5
million, due in one to two years - $28.1 million, due in two to three years -
$54.8 million.  Expected maturities could differ from contractual maturities
since the obligations may have recall or prepayment obligations at par. The
objective of Techne's investment policy is to preserve capital and maintain
liquidity for potential acquisitions, including minority investments in
emerging-stage companies, repurchase of shares and/or potential cash
dividends.  The Company has historically made acquisitions, which required it
to liquidate portions of its available-for-sale investments.   An independent
asset management firm manages the portfolio. Under Techne's investment
policy, the management firm invests in securities that mature or have a
mandatory demand/put or auction feature within three years. The average life
of the portfolio cannot exceed two years.  The Company historically
classified all available-for-sale investments as current assets based on the
highly liquid nature of the investments, the potential use of the investments
in acquisitions, stock repurchases and/or cash dividends.

Chapter 3A, Paragraph 4 of ARB No. 43 states that "For accounting purposes,
the term current assets is used to designate cash and other assets or
resources commonly identified as those which are reasonably expected to be
realized in cash or sold or consumed during the normal operating cycle of the
business."

For classification of individual marketable equity and debt securities
classified as available-for-sale, some have interpreted the ambiguity of ARB
43, using one of two methods (a) based on maturities and management's intent
with regard to those securities (i.e. expectations of sales and redemptions)
or (b) based on whether the securities represent the investment of funds
available for current operations as defined by ARB, Chapter 3, paragraph 4.
Under this scenario management does not need to have a stated intent to sell
such securities within one year (or normal operating cycle).

Techne's historical intent was to have liquidity in its investment portfolio
to effectively meet strategic Company initiatives.  As such, the securities
have been classified as available for sale to match that intent. Upon
reflection of the SEC's staff s comment letter, ARB No. 43 and the strong
cash flow the Company has realized over the near term, the Company has
determined that it will reclassify investments with contractual maturities of
greater than one year as long-term as follows: (in millions):

     				9/30/04			6/30/04
                               ---------                --------
Due within one year             $ 44.3                  $ 42.5
Due in one to three years         89.5                    82.9
                                ------                  ------
Total                           $133.8                  $125.4
                                ======                  ======

Total Assets			$342.6			$325.5

We believe this will provide consistently applied accounting practice. We
plan to classify available-for-sale investments with maturities of greater
than one year as long-term assets in our Form 10-Q filing for the quarter
ended September 30, 2004 (Form NT 10-Q has been filed on November 10, 2004)
and will reclassify the June 30, 2004 investment balance to conform to this
presentation.

                                  ******

We hope that we have adequately addressed item No. 1 in the Comment Letter.
Please contact me at 612-379-6580 (fax) with any questions or comments.

Sincerely,

/s/ Thomas E. Oland
