详细描述:
牛血清白蛋白是一种多肽链,包含大约583个氨基酸残基。在pH5-7时,包含17个链内二硫化物桥和1个巯基基团。该BSA本质上不含球蛋白,尤其不含蛋白酶(>/=98%)。
BSA (Bovine Serum Albumin) is a polypeptide chain consisting of about 583 amino acid residues. At pH5-7 it contains 17 intrachain disulfide bridges and 1 sulfhydryl group. This BSA is essentially globulin free, essentially protease free>/= 98%.
Properties:
Molecular Weight: 66430;
Appearance: white to light brown powder;
CAS Number: 9048-46-8;
Product Usage:
BSA can be dissolved in water or PBS. All assay dilutions are user optimized. Albumins are readily soluble in water and can only be precipitated by high concentrations of neutral salts. When heated to 50 °C or above albumin forms hydrophobic aggregates which do not revert to monomers upon cooling. Extended storage conditions: For extended storage aliquot and freeze at -20 °C or below.
Storage and Handling:
Shipping Conditions: Ambient;
Storage Conditions: +2 to +8 °C
