Gene Information

bovine ... ALB(280717)

Bovine serum albumin is a protein which has a key role in regulating blood colloidal osmotic pressure. A water-soluble protein composed of 583 amino acids, BSA has a calculated molecular weight of 66,430 Daltons. Six α-helices form three homologous domains of BSA. Depending on pH, BSA undergoes reversible conformational isomerization. The native structure of the protein becomes reactive and flexible on heating.

This BSA product is specifically evaluated and tested for the following properties:

• Very low protease content / protease-free
• Very low fatty acid content / fatty acid-free

Protease-free BSA is especially useful for applications like:

• Enzyme assays
• Protein-based assays
• Protease-sensitive techniques that include:

a. Enzyme immunoassay (EIA)
b. Nucleic acid hybridization
c. Radioimmunoassay (RIA)
