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.
A BIOLOGICAL BLOCKING AGENT
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.

The role of BSA in Skin Care and cosmeceutical
BSA is also known to play a role as a structural integrity in the manufacturing of cosmetics. In addition, BSA has shown to interact with hyaluronic acid and attract water to maintain moisture content, thereby enhancing skin elasticity¹. Therefore, BSA can be used as an active ingredient in cosmetics for improving skin conditions, such as skin regeneration, wound healing, and wrinkle improvements¹.
In combination with BIOFAC’s cosmetic grade products, such as Collagen and Elastin products, BSA can have a wide variety of excellent effects in preventing and/or treating skin disease.
Storage and Stability
BIOFAC BSA grades should be stored in original and tightly closed containers at room temperature (not exceeding 25 °C). Retest date is 2 years from date of production, if stored as advised. All products are primarily packed in approved-, light- and airtight aluminum bags followed by fiber drums.
