| Biochem/physiol Actions: | Bovine Serum Albumin (BSA) is a transporter for drugs, hormones and fatty acids. It is a crucial component of the cell culture media and favors embryonic stem cells (hESC) differentiation. BSA displays high solubility and is exploited in the cosmetic and pharmaceutical industry.It is used as a blocking agent in enzyme-linked immunosorbent assay (ELISA). |
| General description: | Bovine serum albumin (BSA) belongs to the serum albumin family. It comprises three domains with two sub-domains under each. It is an α-helical, globular and non-glycosylated protein. BSA has 17-disulfide bonds. |
