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.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
