Albumin, from bovine Cohn fraction V pH CAS:9048-46-8

Bovine albumin, also known as bovine serum albumin (BSA), is a protein derived from the blood of cattle. It is widely used in various applications in the fields of medicine, research, and industry.

Bovine albumin is a highly soluble protein that functions as a carrier for various molecules, such as hormones, fatty acids, and drugs. It has a high affinity for binding to hydrophobic compounds, making it useful in drug formulation and delivery systems.

In research, bovine albumin is often used as a standard reference protein and as a blocking agent in immunoassays, such as enzyme-linked immunosorbent assays (ELISA). It helps to prevent non-specific binding in these assays, improving accuracy and specificity of the results.

Bovine albumin is also used in cell culture as a supplement in growth media. It provides essential nutrients and stabilizes pH levels, supporting cell growth and viability.

In industrial applications, bovine albumin is used in the production of vaccines, cosmetics, and food products. Its properties as a stabilizer, emulsifier, and water-absorbing agent make it valuable for these purposes.
