                  Approximate date of commencement of proposed

The Registrant hereby amends this  Registration  Statement on such date or dates
as may be necessary to delay its effective date until the Registrant  shall file
a further amendment which specifically  states that this Registration  Statement
shall  thereafter  become  effective  in  accordance  with  Section  8(a) of the
Securities  Act of  1933  or  until  the  Registration  Statement  shall  become
effective on such date as the Commission,  acting pursuant to said Section 8(a),
may determine.










         This  Post-Effective  Amendment is being filed to  de-register  537,066
shares of Common Stock (the "Shares") of Techne  Corporation (the  "Registrant")
which were registered under a Registration  Statement on Form S-3,  Registration
No.  33-49156  for  sale  by a  selling  shareholder.  As of the  date  of  this
Post-Effective Amendment, the Shares remain unsold and, since the holding period
under Rule 144(k) has been met with  respect to the Shares,  there is no further
need to maintain the Registration Statement in effect.

Registration  Statement  to be signed on its behalf by the  undersigned,  in the
