hybriGRO SF™ medium enhances hybridoma protein and monoclonal antibody production

MANASSAS, Va., July 6, 2012 --Mediatech Inc., a subsidiary of Corning Incorporated (NYSE:GLW), announced today the introduction of hybriGRO SF™, which enhances the performance of monoclonal antibody-producing hybridoma cells.

Monoclonal antibodies (mAbs) derived from hybridoma cells (cells formed from the fusion of antibody-producing B-cells with myeloma cells) are used extensively in the prevention, diagnosis, and treatment of cancers and other diseases.

hybriGRO SF™ is an advanced serum-free (SF) and animal-derived component-free (ADCF) defined medium which provides the consistency demanded of a defined media in commercial mAb production.

“The use of serum- and animal-origin free defined media is critical in the culture of hybridoma cells for the production of monoclonal antibodies. Our data shows that hybriGRO SF provides a significant increase in cell viability and protein production over existing defined media, with strong protein-product stability in long-term culture,” said Jason Walsh, business director of Mediatech. “The release of hybriGRO SF is a key addition to the Corning cellgro® serum-free portfolio, supporting the needs of life scientists ranging from basic research to biopharmaceutical production.”

In December 2011, Corning acquired Mediatech, which produces the full range of Corning cellgro® media and supplements that are available through Corning Life Sciences sales force and its authorized distributors.
