BSA, RIA / Immunological Grade


Cat. No.: 10226 Category:


General description

Bovine serum albumin (BSA) is a 67 kDa protein with three domains, each consisting of two subdomains. It is α-helical globular and a non-glycosylated protein. BSA is an established transporter for drugs, hormones and fatty acids. It is commonly used blocking agent in enzyme linked immunosorbent assay (ELISA) for preventing non-specific binding of antigens and antibodies to the microtiter plates. The cysteine and tyrosine residues of BSA have high affinity for metal binding.
