Selexis is the only company that enables biopharmaceutical companies to produce ANY recombinant therapeutic protein, because we have the ability to understand and modify our cells to address productivity and expression challenges. We have developed proprietary protein expression tools that can be used with predictability and a high commitment to safety.
Selexis SA is a scientific pioneer and global leader in mammalian (suspension-adapted CHO-K1) cell line generation that has been setting the pace of innovation in protein expression and establishing new benchmarks in bioproduction for more than a decade.
Unleashing the power of novel protein therapeutics to transform the care of and prospects for millions of patients who suffer from life-threatening diseases depends heavily on continued advances in technologies and methods for protein expression. This is particularly critical for medicines that are based on recombinant proteins, such as monoclonal antibodies, and difficult-to-express proteins, including Fc-fusion proteins, bi-specific monoclonal antibodies, and novel scaffolds.
With unparalleled proprietary technology and highly specialized expertise that can translate scientific innovation into life-saving medicines, Selexis is a leading provider of cell line expression technologies that are vital to the discovery and development of therapeutic proteins. Bolstered by our novel, proprietary SUREtechnology Platform™, we have the capabilities to facilitate the rapid, stable, safe, and cost-effective production of virtually any recombinant protein. Our combination of proprietary technology and unparalleled expertise provides seamless integration of the bioproduction continuum, spanning discovery to commercialization.
