A story on Cytyc Corp.’s purchase of Digene Corp. in the Feb. 20, 2002, edition of BioWorld Today should have labeled the value of the deal at $554 million. The story included the $77 million cash portion of the deal and the 23 million shares involved, but mistakenly did not include the value of the stock when totaling the deal value.

Editor’s Note: The change will be made Monday in BioWorld Online.
