Bovine Serum Albumin (BSA)

With more than 70 years’ of manufacturing expertise, BIOFAC is a reliable supplier of various BSA grades in bulk quantities to loyal customers around the world.


Bovine Serum Albumin (BSA) is a protein derived from bovine plasma. It is a small and stable protein with non-reactive effects, which is the reason for its use as a protein standard in numerous applications in immunology, biochemistry, and biotechnology. As BSA binds to non-specific binding sites, thereby facilitating the antibody coupling with the antigens of interest, BSA is used in immunohistochemistry, ELISA, and Western Blotting applications. Additionally, BSA can be used as a stabilizer and as anutrient to support cell and microbial growth in culture media.


By taking advantages of our 75 years of expertise in the pharmaceutical and nutraceutical industries, BIOFAC produces a wide variety of BSA grades for your research and manufacturing needs:
