Produktbeschreibung

Bovine serum albumin can be used as a diluent or a blocking agent in numerous applications including ELISA, blots and immunohistochemistry. In restriction digests, bovine serum albumin is used to stabilize some enzymes during digestion of DNA and to prevent adhesion of the enzyme to reaction tubes and other vessels. BSA doesnt affect other enzymes that do not need it for stabilization and is used because of its stability. Albumins are readily soluble in de-ionized water and can only precipitated by high concentrations of neutral salts. Bovine Serum Albumin help stabilize other solubilized proteins. Bovine Serum Albumin (BSA) is readily coagulated with heat. BSA as with other albumins are acidic proteins which occur in abundance in body fluids and tissues and is easily crystallized.
