Descripción

General description

BSA belongs to the serum albumin family, comprising three domains with two sub-domains under each. BSA is an α-helical, globular, and non-glycosylated protein with 17-disulfide bonds.

Albumin, Bovine Serum, (BSA) Cohn Fraction is purified by cold ethanol precipitation (Cohn extraction) and by heat treatment to remove lipids and fatty acids. It is a single carbohydrate-free polypeptide and the most abundant (comprising ~60%) of the plasma proteins. BSA regulates the maintenance of osmotic pressure.

Biochem/physiol Actions

Bovine serum albumin (BSA) transports sparingly soluble physiological substances, especially long-chain fatty acids, bilirubin, drugs, hormones, and fatty acids. It acts as a blocking agent in enzyme-linked immunosorbent assay (ELISA). BSA is a vital component of the cell culture media and boosts embryonic stem cells (hESC) differentiation.

Physical form

30% solution in 0.8% NaCl, 0.1% NaN₃, pH 7.2, sterile-filtered.
