what is the difference between Human Serum Albumin and Bovine Serum Albumin?

Answer 1

Human serum albumin is the most abundant protein in human blood plasma. It is produced in the liver. The reference range for albumin concentrations in blood is 30 to 50 g/L (3.0 to 5.0 g/dL). It has a serum half-life of approximately 20 days. It has a molecular mass of 67 kDa.

Bovine serum albumin, Bovine Albumin, BSA: A serum albumin protein that can be used as a diluent or a blocking agent in numerous applications including ELISAs (Enzyme-Linked Immunosorbent Assay), blots and immunohistochemistry. It is also used as a nutrient in cell and microbial culture. In restriction digests, BSA is used to stabilize some enzymes during digestion of DNA and to prevent adhesion of the enzyme to reaction tubes and other vessels. This protein does not affect other enzymes that do not need it for stabilization. BSA is used because of its stability, its lack of effect in many biochemical reactions, and its low cost since it is readily available in large quantities as it is purified from bovine blood, a byproduct of the beef industry.

Serum albumin from cows, commonly used in in vitro biological studies.

Answer 2

One comes from humans and one comes from cows. They are homologous proteins which serve the same function in the two species.

Answer 3

HSA is a kind of protein that present in human blood,BSA is extracted from oxes or cows.
