CHIRON® Recombinant Proteins a Local Partner in the San Francisco Bay Area

The biomanufacturing legacy of the Grifols campus in Emeryville, California, began with Chiron and Cetus in the 1980s, with innovative advancements in yeast expression, viral discovery and the development of PCR. Three decades of process development and manufacturing experience is the foundation of the business today at CHIRON® Recombinant Proteins.

CHIRON® Recombinant Proteins partners with companies interested in developing complex proteins into therapeutics, vaccines or diagnostics. Our state-of-the-art GMP biological manufacturing CMF facility located in the San Francisco Bay Area is well positioned to provide long-term, high-quality, commercial manufacturing of recombinant biologic drug substances to our customers, regardless of their global location. This location, in one of the major U.S. biotech hubs –– home to many emerging biotechnology companies lacking extensive internal development and manufacturing resources –– provides us with an opportunity to effectively serve a host of local customers.

CHIRON® Recombinant Proteins is staffed by highly experienced and talented people with diverse expertise and educational backgrounds within the field of biotechnology. Our staff welcomes the opportunity to have face-to-face visits with clients where new ideas can be discussed. With their significant tech transfer expertise and access to the state-of-the-art facilities and equipment within the CMF and new pilot plant, including R&D, process development and analytical laboratories, our scientists can rapidly identify solutions for our CDMO clients.
