牛血清白蛋白–Heat Shock, Fatty Acid Free pH 7.0 | 貨號7921

Bovine Serum Albumin – Heat Shock, Fatty Acid Free, pH 7.0

產品介紹: 該BSA通過專有的heat shock進行了純化。 BSA約佔動物血清(animal serum)中所有蛋白質的60％。 它通常用於細胞培養方案中，特別是在需要補充蛋白質且不需要血清的其他成分時。 它有助於穩定酶和其他蛋白質，以防止蛋白水解(proteolysis)和變性(denaturation)，特別是當蛋白質以低濃度存在時。 在細胞培養中，其主要作用是作為小分子的載體。 由於其帶負電荷，BSA結合水，鹽，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成為有效清除介質中有毒物質（包括熱原）的清除劑。

 

Highlights	SOURCE: The raw material used to manufacture this lot was derived exclusively from USDA-regulated abattoirs located in the United States. The animals received ante-mortem and post-mortem inspection under a licensed veterinarian’s supervision and were certified at the time of slaughter as free of infectious or contagious diseases and injurious parasites. PURITY: ≥ 96% by SDS-PAGE analysis MOL. WEIGHT: ~ 66.43 kDa FORM: Off-white powder ALBUMIN CONTENT: ≥ 98% by electrophoresis. pH: 7.0 ± 0.5 MOISTURE: ≤ 5.0% HEAVY METALS: ≤ 20 ppm ASH: ≤ 3% FREE FATTY ACIDS: < 0.02% SOLUBILITY: ~ 50 mg/ml in water, with 15 min manual stirring. APPLICATIONS/ADVANTAGES: • Normally used in Serum Free Media as a carrier protein for trace elements, fatty acids, hormones and growth factors. • Allows the formulation of albumin with specific fatty acids to enhance cell culture system performance. • A preferred alternative in assays where the presence of lipids or fatty acids compromises hormone or cholesterol readouts.
