Affinity BioReagents

Affinity BioReagents (ABR) was a prominent developer and supplier of research antibodies, proteins, and peptides for the life sciences community. Founded in 1989 and based in Golden, Colorado, the company built a reputation for high-quality reagents targeting heat shock proteins, steroid receptors, and membrane transporters. In 2008, Affinity BioReagents was acquired by Thermo Fisher Scientific, leading to the integration of its product portfolio into the Thermo Scientific Pierce and Invitrogen brands. The company's legacy continues through its widely cited products used in proteomics, cell signaling, and molecular biology research. Prior to its acquisition, ABR was recognized for its extensive catalog of over 35,000 products and its commitment to technical support for academic and industrial researchers.
