Solubility: Albumins are readily soluble in deionized water and can only precipitated by high concentrations of neutral salts. Bovine Serum Albumin (BSA) helps stabilize other solubilized proteins. Bovine Serum albumin (BSA) is readily coagulated with heat. Bovine serum albumin as with other albumins are acidic proteins which occur in abundance in body fluids and tissues and is easily crystalized.

What is Bovine Serum Albumin (BSA)?: Bovine serum albumin (BSA) can be used as a diluent or a blocking agent in numerous applications including ELISAs (Enzyme-Linked Immunosorbent Assay), blots and immunohistochemistry. In restriction digests, bovine serum albumin BSA is used to stabilize some enzymes during digestion of DNA and to prevent adhesion of the enzyme to reaction tubes and other vessels. Bovine Serum Albumin does not affect other enzymes that do not need it for stabilization. BSA is used because of its stability.
