Oct. 5, 2009 (PR Newswire) --

ST. LOUIS and RICHMOND, Calif., Oct. 5 /PRNewswire-FirstCall/ -- Sigma-Aldrich Corporation (Nasdaq: SIAL) and Sangamo BioSciences, Inc. (Nasdaq: SGMO) today announced a major expansion of their existing license agreement to include the exclusive rights to develop and distribute zinc finger DNA binding protein (ZFP)-modified cell lines for commercial production of protein pharmaceuticals. Additionally, Sigma-Aldrich licensed rights to certain ZFP-engineered transgenic animals for commercial applications.

"The zinc finger technology platform developed by Sangamo is a core component of Sigma-Aldrich's growth strategy into high-value biologic tools," said Jai Nagarkatti, Sigma-Aldrich's Chairman, President and CEO. "We have experienced tremendous interest from the academic and biotechnology research community in our CompoZr(TM) zinc finger nuclease (ZFN) platform of reagents. Expanding our capability to provide ZFN-modified cells for the commercial production of therapeutic proteins and vaccines takes us into markets with enormous commercial potential, and we fully intend to maximize the value of these assets."

"ZFN-based gene editing is rapidly emerging as a critical tool in modern biotechnology," said David Smoller, Ph.D., President of Sigma-Aldrich's Research Biotech Business Unit. "The ability to modify genes in essentially any cell type has been established. In addition, we are now able to generate transgenic animals in species in which it was previously impossible to efficiently and specifically carry out genome modification. This opens up endless possibilities for application and commercialization of the ZFP technology platform."

"We are delighted with our partnership with Sigma-Aldrich," said Edward Lanphier, Sangamo's President and CEO. "Sigma-Aldrich has been aggressively developing, marketing and distributing ZFP-based products through their CompoZr website, and we anticipate the same success in these expanded markets of cell line engineering and transgenic animal products. Sangamo's business model enables us to access non-dilutive funding for our core ZFP Therapeutic(TM) programs by monetizing the industrial applications of our ZFP technology with a focused and committed partner. Sigma-Aldrich has proven to be just that."
