Bovine Serum Albumin (BSA) solution is widely used in biochemical and molecular biology research as a protein standard in assays like the Bradford and Lowry protein assays. It serves as a blocking agent in immunoassays, such as ELISA and Western blotting, to prevent non-specific binding of antibodies. In cell culture, BSA is added to media to provide nutrients and stabilize enzymes and other proteins. It is also utilized as a stabilizer in PCR and other enzymatic reactions to enhance efficiency and reproducibility. Additionally, BSA is employed in diagnostic kits and as a carrier protein for small molecules in drug delivery studies. Its versatility makes it a critical component in various scientific applications.
