Description_x000D_
General description_x000D_
Bovine serum albumin is a model protein in various studies and is made up of 583 amino acids. It is a water-soluble protein with a molecular weight of 66.4kDa. Six α-helices form three homologous domains of BSA. Depending on pH, it undergoes reversible conformational isomerization. The native structure of the protein becomes reactive and flexible on heating._x000D_
Application_x000D_
• Bovine Serum Albumin has been used in solution prepared for the isolation of heart mitochondria._x000D_
• It has been used in the cytotoxicity assay buffer._x000D_
• It has been used for the induction of protein overload nephropathy in rats._x000D_
Packaging_x000D_
1, 5 kg in poly drum_x000D_
10, 50, 100, 500 g in poly bottle_x000D_
Biochem/physiol Actions_x000D_
Certain conformational and primary-sequence epitopes of BSA are suspected allergens in human beef and milk allergies._x000D_
Preparation Note_x000D_
Often referred to as Cohn fraction V; this product is prepared by a modified method of the Cohn cold ethanol fractionation method._x000D_
Serum albumin may be referred to as Fraction V. This naming convention is taken from the original Cohn method of fractionating serum proteins using cold ethanol precipitation. Serum albumin was found in the fifth ethanol fraction using Cohn′s method. Since then, the term "Fraction V" has been used by some to describe serum albumin regardless of the method of preparation. Others have used this term to describe serum albumin purified by ethanol fractionation methods that have been highly modified since the original Cohn method was described. Sigma-Aldrich manufactures and distributes serum albumins purified from a variety of primary methods including the true Cohn fractionation method, modified ethanol fractionation methods, heat shock and chromatography. Additional purification steps may include crystallization or charcoal filtration.
