Sigma-Aldrich Bovine Serum Albumin, 500 g Net Content, 9048-46-8, 66 kDa, Lyophilized Powder Form, White to Light Yellow to Light Brown, 2 to 8 deg C, Albumin Bovine Serum, Bovine Albumin, BSA, 7 pH, >=98% Bovine Biological Source. Bovine serum albumin (BSA) has an important role in the regulation of blood colloidal osmotic pressure. BSA is the major protein in bovine serum and is composed of 583 amino acids with a calculated molecular weight of 66430 Daltons. BSA is used in many different applications and fields, such as protein quanti-tation (as a standard), immunochemistry (as a blocking agent), cell culture (as a nutrient). This particular BSA is specifically evaluated and tested to have very low protease content/for protease-free status. Protease-free BSA may be used in applications like enzyme assays, protein-based assays. Protease-sensitive techniques that include a) enzyme immunoassay (EIA), b) nucleic acid hybridization, c) radioimmunoassay (RIA) - SIAL (Additional S&H Or Hazmat Fees May Apply)
