This Low Endotoxin Albumin is available in the CellMaxx™ Albumin Sample Pack (catalog number 02CELLMAXXS)....Read More
牛血清白蛋白(Bovine Serum Albumin, BSA)是牛血清中的一种球蛋白,又称第五组分(需要注意的是,第五组分并不是BSA的一种组份,而是Edwin J. Cohn教授早期从血液中通过特定的分离技术得到5种组份,其中第五种就是白蛋白),CAS号为9048-46-8,包含583个氨基酸残基,分子量为66.430 kDa,等电点为4.7。牛血清白蛋白在生化实验中有广泛的应用,例如在western blot中作为封闭试剂。血液中的白蛋白主要起维持渗透压作用、PH缓冲作用、载体作用和营养作用。在动物细胞无血清培养中,添加白蛋白可起到生理和机械保护作用和载体作用。
