CellMaxx™ Bovine Albumin is chromatographically purified from New Zealand-sourced bovine plasma in an ISO quality system assuring complete traceability and consistent high quality. This albumin has very low endotoxin and low IgG to simplify downstream purification, is tested for the absence of viruses according to 9CFR and has the highest possible biosafety level. The albumin supports growth of stem cells and increases protein production from hybridoma cells. Form: Powder Purity: ≥97% w/w total protein Total Protein: ≥95% w/w total protein Moisture: ≤5% w/w Endotoxin: ≤1 EU/mg IgG: ≤0.05 mg/g total protein Bioburden: ≤100 cfu/g Mycoplasma/Virus: None detected
This Low IgG Albumin is available in the CellMaxx™ Albumin Sample Pack (catalog number 02CELLMAXXS).
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。
