Biosource

BioSource International was a prominent life science company specializing in the development and manufacture of reagents for functional genomics, proteomics, and drug discovery. The company offered an extensive portfolio of antibodies, ELISA kits, cytokines, and growth factors, with a particular focus on phosphorylation-specific antibodies and multiplex assays for cell signaling research. BioSource's products were widely utilized by academic and pharmaceutical researchers to investigate disease pathways in oncology, immunology, and neurobiology. In 2005, the company was acquired by Invitrogen, which subsequently became part of Thermo Fisher Scientific, where the BioSource product line continues to support protein analysis and cell biology applications.
