Repligen GmbH

Repligen is a bioprocessing-focused life sciences company bringing over 30 years of expertise and innovation to our customers. We are inspiring advances in bioprocessing through the development and commercialization of high-value products and flexible solutions that address critical steps in the production of biologic drugs, principally monoclonal antibodies.

Our core Protein A affinity ligands business is complemented by an expanding suite of technology-leading bioprocessing products that we sell direct to biopharmaceutical companies and contract manufacturers worldwide. All of our bioprocessing products are meaningfully differentiated from alternatives to the benefit of our customers. Our Protein A ligands are used to purify over 50 monoclonal antibody-based drugs on the market and more than 300 in clinical development. Our XCell™ ATF cell concentration device, and LONG® cell culture supplements are at the forefront of innovation in bioprocessing. To provide customers with the broadest selection of OPUS® pre-packed chromatography columns from bench-scale to production-scale, Repligen acquired Atoll GmBH of Weingarten, Germany, solidifying Repligen as a leading supplier in this fast-growing segment.
