17 September 2008 - International law firm Mayer Brown acted as a transaction counsel for Cologne-based DIREVO Biotech AG on its acquisition by Bayer HealthCare AG. With the acquisition of the biotech company specialized in protein engineering, Bayer strengthens the research competence in biologicals of its pharmaceutical division Bayer Schering Pharma. Closing of the deal of a value of 210 million Euro is projected for end of September 2008.
