MONTREAL, April 19, 2007 (PRIME NEWSWIRE) -- Viropro Inc. (OTCBB:VPRO) ("Viropro") today provides an update to the financial community and to its shareholders regarding its March 19, 2007 announcement for the development of one of the company's main products, a targeted high volume sales Monoclonal Antibody.

"Step 1 of the seven-month development program with the Biotechnology Research Institute has been successfully completed. Monoclonal antibody genes have been inserted into our proprietary expression vectors, and the antibody has been shown to be properly produced into various cellular systems. The selection of initial stable high producing cell lines has begun. These preliminary results have been validated by an independent laboratory at Laval University, Quebec City," stated Dr. Jean-Marie Dupuy, President and CEO of Viropro. "The development program is going as originally planned and the selection of a set of high producing stable clones is in progress. This will allow Viropro to start-up the production process development phase," added Dr. Dupuy.

The company will then out-license this product to various biopharmaceutical manufacturing partners. Discussions to this effect are progressing well. Significant out-licensing revenues are expected starting in 2007.
