Bovine Serum Albumin

CAS Number: 9048-46-8

 

Bovine Serum Albumin (BSA) is a non-glycosylated protein of 66 kDa. Produced by the liver, BSA is the most abundant protein in plasma. Albumin has a key role for maintaining oncotic pressure, and is the main carrier for low molecular weight compounds such as fatty acids and hormones.

Due to its versatile properties, Bovine Serum Albumin (BSA) plays a major role in numerous biological applications such as blood grouping, cell culture or immunoassays (ELISA, RIA,…).

 


H2B manufactures highly purified Bovine Serum Albumin (BSA) obtained by a proprietary Heat-Shock method.

Bovine plasma used for the manufacture of H2B Bovine Serum Albumin (BSA) is collected from French healthy cattle declared free from BSE disease in its clinical forms. It is sourced in EU-approved French slaughterhouses.

Bovine Serum Albumin (BSA) is used as a protein standard, stabilizer and blocking or buffering agent.

 


Thanks to over 20 years of manufacturing this product, H2B guarantees a great expertise and high batch-to-batch repeatability.

H2B offers a complete range of Bovine Serum Albumin (BSA) to meet your needs, available in both liquid (30% ready-to-use solution) and lyophilized forms.
