Bovine Serum Albumin , BSA (heat shock process) | 貨號7920-100

Bovine Serum Albumin – Heat Shock, Protease DNASE Free, pH 7.0

產品介紹: 該BSA純化經由heat shock process。 BSA約佔動物血清中所有蛋白質的60％。它通常用於細胞培養，特別是在需要補充蛋白質(protein supplementation)且不需要血清(serum)的其他成分時。當蛋白質以低濃度存在時，有助於穩定酶和其他蛋白質，以防止蛋白水解(proteolysis)和變性(denaturation)。在細胞培養中，其主要作用是作為小分子(small molecules)的載體(carrier)。由於其帶負電荷(negative charge)，BSA會結合水(water)，鹽(salts)，脂肪酸(fatty acids)，維生素(vitamins)和激素(hormones)，然後在組織和細胞之間攜帶這些結合的成分。結合能力還使BSA成為從介質中去除有毒物質（包括熱原pyrogens）的有效清除劑。
