Bovine Serum Albumin (BSA) | 合法醫療器材資訊網

Supplementation of cell culture media with BSA protein can benefit cell growth and survival, especially when using serum-free media[1]. Bovine serum albumin binds essential molecules present in the media (e.g., fatty acids, hormones, peptides), allowing for efficient delivery of these molecules into cultured cells. The antioxidative properties of BSA protein can also reduce cellular stress and damage.

Thermo Fisher Scientific offers a variety of Gibco BSA products optimized for supplementing cell culture media, including AlbuMAX Lipid-Rich BSA, which can reduce or eliminate the need for supplementation of cell culture media with serum.

BSA protein is also commonly used for blocking during immunoassays, including ELISA and western blotting. As a single protein, BSA is less likely to exhibit cross-reactivity with antibodies than milk, which is a complex protein mixture. In addi...
