Item 1.01  Entry into a Material Definitive Agreement

Attached as Exhibit 99.1 is a copy of the press release issued by Techne 
Corporation (the "Company") on March 2, 2005, announcing the repurchase of 
approximately 2.9 million shares of common stock for $100 million.  The 
transaction was completed through a financial intermediary pursuant to an 
accelerated share buyback ("ASB") program.  The shares were purchased at an 
initial price of $34.45 per share, subject to a market price adjustment 
provision expected to be settled in December 2005.  At the end of the settlement
period, the Company will receive or pay the price adjustment based on the volume
weighted average price of the shares traded on the Nasdaq prior to the 
settlement date.  Approximately two-thirds of the shares purchased pursuant to 
the ASB program are subject to a collar, which effectively sets a minimum and 
maximum price the Company will be obligated to pay for such shares.  The collar 
was established in exchange for an upfront payment.
