China High Purity Biochemical Reagent factory BSA serum albumin (BSA or "Fraction V") is a serum albumin protein derived from cows. It is often used as a protein concentration standard in lab experiments. The nickname "Fraction V" refers to albumin being the fifth fraction of the original Edwin Cohn purification methodology that made use of differential solubility characteristics of plasma proteins. By manipulating solvent concentrations, pH, salt levels, and temperature, Cohn was able to pull out successive "fractions" of blood plasma. The process was first commercialized with human albumin for medical use and later adopted for production of BSA.

Bovine serum albumin (BSA), also known as the fifth group, is a kind of globulin in bovine serum, containing 583 amino acid residues, molecular weight of 66.430 kDa, isoelectric point of 4.7. Bsa has been widely used in biochemical experiments, for example as a Blocking agent in western blot. Composition structure A simple protein in bovine serum, the main component of blood (38g/100ml), with a molecular weight of 68kD. Isoelectric point 4.8. It contains 16% nitrogen and 0.08% sugar. It contains only hexaosaccharide and hexaosamine, and contains only 0.2% fat. Albumin is composed of 581 amino acid residues, of which 35 cysteines form 17 disulfide bonds, with a free sulfcapto group at position 34 of the peptide chain. Albumin can bind to a variety of cations, anions and other small molecules. Albumin in blood mainly plays a role in maintaining osmotic pressure, PH buffer, carrier and nutrition. In the serum-free culture of animal cells, the addition of albumin can provide physiological and mechanical protection and carrier function. BSA IS COMMONLY USED AS a stabilizer IN STORAGE AND reaction solutions for limiting or modifying enzymes, because some enzymes are unstable or have low activity at low concentrations. After the addition of BSA, it may play the role of "protection" or "carrier", and the activity of many enzymes can be greatly increased after the addition of BSA. Enzymes that do not require BSA are generally unaffected by the addition of BSA. For most substrate DNA, BSA can make the enzyme digestion more complete and can achieve repeated cleavage. At 37 掳 C, BSA can make the enzyme more stable when the digestion reaction is longer than 1h, because many restriction enzymes can only survive for 10"20min or less at 37 掳 C in reaction buffer without BSA. BSA can bind metal ions and other chemicals in buffer or substrate DNA that inhibit restriction enzyme activity. The role of BSA as a buffer for endonuclease 1.BSA is an enzyme stabilizer, preventing enzyme decomposition and non-specific adsorption; 2. The BSA can reduce the degeneration of some enzymes, can alleviate some adverse environmental factors such as heat, surface tension and chemical factors of degeneration and as for the mechanism is not very clear to me, perhaps because it has 17 disulfide bond in the structure, and a thiol, thiol chemistry is very lively, disulfide bond has the effect of oxidation reduction, therefore with a variety of cationic, Anions bind to small molecules; 3.BSA can prevent enzyme adsorption to the tube wall and loss.China High Purity Biochemical Reagent factory website:http://www.hbynm.com/high-purity-biochemical-reagent/
