Bovine Serum Albumin (BSA) also referred as Fraction V (as it has been originally found in the fifth ethanol fraction using Cohn′s cold ethanol precipitation
method) is a Serum Albumin Protein derived from bovine serum with a molecular weight of 66.4kDa. It is a water-soluble protein which consists of 583 amino acids. It consists of three homologous
domains which have been formed by six α-helices.
Albumin is the most abundant protein of the serum (about 60% of the total protein content of plasma). which regulates the osmotic pressure and pH of blood, and transports a wide variety of endogenous and exogenous compounds such as fatty acids, metal, amino acids, steroids and drugs.
BSA, Low endotoxin level (contains less than 0.5 EU/mg endotoxin), is protease, IgG and non-esterified fatty acids free and is ideal option for most cell culture applications and assays that require low endotoxin levels.
