Bovine Serum Albumin (BSA) is widely used in various laboratory and industrial applications due to its stability and versatility. In biochemical research, it serves as a standard protein for calibration in assays like ELISA and Bradford protein assays, ensuring accurate quantification of proteins. BSA is also employed as a blocking agent in immunoassays to prevent non-specific binding, enhancing the specificity of antibody-antigen interactions. In cell culture, it acts as a nutrient supplement, providing essential amino acids and promoting cell growth. Additionally, BSA is used in molecular biology as a stabilizer for enzymes and proteins during storage and reactions. Its ability to bind and transport molecules makes it valuable in drug delivery systems and diagnostic applications.
