CATEGORY

Bovine Serum Albumin (BSA) is a globular protein isolated and purified from bovine serum, belonging to the serum albumin family. It is the most abundant protein in bovine plasma, accounting for approximately 50% to 60% of the total plasma protein. Synthesized in the liver, BSA possesses high water solubility, stability, and binding capacity; it is capable of binding to a wide variety of endogenous and exogenous substances, thereby playing significant physiological roles in maintaining plasma osmotic pressure, transporting nutrients, providing antioxidant protection, and regulating immune responses.

Function

In the field of cell culture, BSA plays a pivotal role in serum-free media, serving as a carrier for growth factors, hormones, and lipids, while also maintaining cellular osmotic pressure and protecting cells from mechanical damage.

In molecular biology, BSA enhances the stability of Taq polymerase in PCR reactions; furthermore, in DNA restriction digests, it prevents restriction endonucleases from adsorbing to tube walls or undergoing denaturation.

In immunoassays, BSA is widely utilized as a blocking agent in Western blots, ELISAs, and immunohistochemistry to prevent the non-specific binding of antibodies.

In the diagnostic sector, it functions as a stabilizer for enzyme conjugates, a matrix for calibrators, and a key component in immunoassay kits.

Additionally, in the cosmetics industry, BSA is employed as a humectant and stabilizer; in the food industry, it serves as a foaming agent, emulsifier, and nutritional fortifier.
