| Application: | Bovine Serum Albumin solution has been used: • to study the effects of plasma protein on sulfated glycosaminoglycans (sGAGs • to histologically evaluate the implanted allogeneic mesenchymal stem cells (MSCs) alginate constructs • as a component of phosphate-buffered saline (PBS) to treat red blood cells (RBC) for sample preparation |
| Biochem/physiol Actions: | Bovine Serum Albumin (BSA) is the most widely used blocking agent in enzyme-linked immunosorbent assay (ELISA). It is also the main constituent of cell culture media. BSA promotes the differentiation of human embryonic stem cells (hESC) differentiation and assists the circulation of drugs, hormones, and fatty acids. |
| General description: | Bovine serum albumin (BSA) is bound in a single chain cross-linked with 17 cysteine residues. It comprises three homologous, structurally different domains and two sub-domains each. This globular, α-helical, non-glycosylated protein is produced in the liver. |
