Product Overview

Sigma-Aldrich Bovine Serum Albumin (BSA) Solution is a high-purity, sterile-filtered 35% solution in Dulbecco’s Phosphate-Buffered Saline (DPBS), designed for cell culture and biochemical applications. This BioXtra-grade BSA is extensively endotoxin-tested, making it suitable for mammalian cell culture, blocking applications, and protein stabilization.

BSA is a single polypeptide chain of approximately 583 amino acid residues, stabilized by 17 disulfide bonds and one free sulfhydryl group, ensuring structural integrity and functional stability in biological systems.

This BSA solution is widely used in serum-free culture media formulations, immunological assays, and biochemical applications requiring a stable protein carrier.
