Basic Info

Product Description

Bovine serum albumin (BSA), a globulin in bovine serum, contains 607 amino acid residues, has a molecular weight of 66.446KDa and an isoelectric point of 4.7. Bovine serum albumin has a wide range of applications in biochemical experiments.contribute to the stability and activity of Taq enzyme in the PCR system, and to increase the efficiency of PCR.BSA is generally used as a stabilizer in storage solutions and reaction solutions for restriction enzymes or modified enzymes, because some enzymes are unstable or have low activity at low concentrations. After adding BSA, it may play a "protective" or "carrier" role. Many enzymes can greatly increase their activity after adding BSA. Enzymes that do not need to add BSA will not be affected by the addition of BSA. For most substrate DNA, BSA can make the digestion more complete, and can achieve repeated cutting. At 37ºC, when the digestion reaction exceeds 1h, BSA can make the enzyme more stable, because in the reaction buffer without BSA, many restriction enzymes can only survive for 10"20min or even shorter time at 37ºC And BSA can bind to metal ions and other chemicals in the buffer or substrate DNA that inhibit the activity of restriction enzymes.
