Bovine serum albumin (BSA), a globulin in bovine serum, contains 607 amino acid residues with a molecular weight of 66.446KDa and an isoelectric point of 4.7. Bovine serum albumin has been widely used in biochemical experiments. The total length of BSA precursor protein is 607 amino acids. The precursor protein removes 18 signaling peptides and 6 propeptides from the N terminal to form a mature BSA protein with 583 amino acids and a molecular weight of about 66.5kDa. The surface of BSA contains a large number of carboxyl and amino groups, which can be used to bind the activated groups on the surface, and can be used as a carrier of small molecules. BSA is coupled with antibodies to form carrier-haptens conjugate.
