                 PART I - REGISTRANT INFORMATION

Full Name of Registrant: Techne Corporation

Former Name if Applicable:

Address of Principal Executive Office:  614 McKinley Place NE

City, State and Zip Code:  Minneapolis, MN  55413


                PART II - RULES 12b-25(b) AND (c)

     If the subject report could not be filed without unreasonable effort or
expense and the registrant seeks relief pursuant to Rule 12b-25(b), the
following should be completed.  (Check box if appropriate)

   | (a) The reasons described in reasonable detail in Part III of this
   |     form could not be eliminated without unreasonable effort or
   |     expense;
   |
   | (b) The subject annual report, semi-annual report, transition report
/X/|     on Form 10-K, Form 20-F, 11-K, Form N-SAR, or portion thereof, will
   |     be filed on or before the fifteenth calendar day following the
   |     prescribed due date; or the subject quarterly report of transition
   |     report on Form 10-Q, or portion thereof will be filed on or before
   |     the fifth calendar day following the prescribed due date; and
   |
   | (c) The accountant's statement or other exhibit required by Rule
   |     12b-25(c) has been attached if applicable.


                    PART III - NARRATIVE

     State below in reasonable detail the reasons why the Form 10-K and Form
10-KSB, 20-F, 11-K, 10-Q and Form 10-QSB, N-SAR, or the transition report or
portion thereof, could not be filed within the prescribed time period.

     The Registrant needs more time than originally anticipated to gather all
of the financial information necessary to complete the Form 10-Q for the
quarter ended September 30, 2004. The Registrant is analyzing its
classification of available-for-sale investments as current assets since a
portion of the portfolio has contractual maturities of more than one year.
Until the analysis is complete, KPMG LLP, the Registrant's independent
registered public accounting firm, has not complete their review for the three
months period ended September 30, 2004.
