	Re:  Registration Statement on Form S-8


Ladies and Gentlemen:

	We are acting as corporate counsel to Techne Corporation (the "Company")
in connection with the original registration by the Company on Form S-8 (the
"Registration Statement") under the Securities Act of 1933, as amended (the
"Act") of 3,000,000 shares of Common Stock (the "Shares") issuable pursuant to
the Company's 2010 Equity Incentive Plan (the "Plan").

	In acting as such counsel and for the purpose of rendering this opinion,
we have reviewed copies of the following, as presented to us by the Company:
(i) the Company's Articles of Incorporation; (ii) the Company's By-Laws; (iii)
certain corporate resolutions certified by the Secretary of the Company as
having been adopted by the Board of Directors and shareholders of the Company
pertaining to the approval of the Plans; (iv) the Plan; and (v) the
Registration Statement.

       Based on, and subject to, the foregoing and upon representations and
information provided by the Company or its officers or directors, it is our
opinion as of this date that, upon issuance and delivery of the Shares against
receipt by the Company of the consideration for the Shares pursuant to the
terms of the Plan, the Shares will be validly issued, fully paid and
nonassessable.

	We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.  In giving such consent, we do not hereby admit that we
are in the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission.

                                Very truly yours,

                                FREDRIKSON & BYRON, P.A.
