Companies Agree to Expanded Access to ZFN Technology To Potentially Improve

Protein Production

RICHMOND, Calif., Feb. 27 /PRNewswire-FirstCall/ -- Sangamo BioSciences, Inc. (Nasdaq: SGMO) today announced that it has entered into a second Research and License Agreement with Genentech, Inc. expanding on the original agreement to include additional targets for potential improvement of production cell lines using Sangamo's proprietary zinc finger DNA-binding protein nuclease (ZFN) technology.

"We are pleased to expand our relationship with Genentech, a company that has always operated at the cutting edge of innovative development," said Edward Lanphier, Sangamo's president and chief executive officer. "Under this second non-exclusive, research and commercial license agreement, Sangamo will design and engineer additional ZFNs that target genes identified by Genentech to potentially improve protein pharmaceutical production in mammalian cells. This further agreement strengthens our belief that there is a growing appreciation of the value of our technology which provides a rapid, reliable and highly specific method to efficiently alter genes in eukaryotic cells."

Sangamo announced a strategic relationship with Sigma-Aldrich in July 2007 aimed at commercializing the research aspects of the ZFP technology in several areas, including the field of protein production. "As a Sangamo partner, Sigma is fully committed to bringing this powerful new technology to the scientific research community in the form of future products and services, which we believe will lead to a new era of scientific endeavor," said David Smoller, Ph.D., President of Sigma-Aldrich's Research Biotech Unit.
