General description
牛血清白蛋白（BSA、组分V、不含脂肪酸）适用于免疫诊断分析。它设计用于血清学检测、放射免疫测定和激素反应研究。它也适用于结合和运输研究。BSA采用冷乙醇提取法（Cohn法）制备。pH值：6.8-7.4。
牛血清白蛋白（BSA）是一种非糖基化球状α-螺旋蛋白，属于血清白蛋白家族。它由三个结构域组成，每个结构域有两个子结构域，并且具有17个二硫键。
Application
牛血清白蛋白（组分V、不含脂肪酸）已用作：
- 一种组分以用于各种细胞免疫电子显微镜（IEM）的阻断缓冲液
- 线粒体隔离缓冲液（MIB）和线粒体测定液（MAS），以捕获脂肪组织均质化过程中释放的游离脂肪酸
- 一种阻断缓冲液，以对食管上皮（EE）进行免疫荧光全旦染色
Biochem/physiol Actions
牛血清白蛋白（BSA）是细胞培养基中最重要的成分，有助于胚胎干细胞（hESC）的分化。它有助于药物、激素和脂肪酸的运输。BSA也被用作酶联免疫吸附试验（ELISA）的阻断剂。
Preparation Note
可能需要长达24小时才能完全溶解。
在复溶后存放于冰箱（4°C）。可能添加0.1% NaN₃作为防腐剂。储备溶液在4°C下可稳定保存3个月。

Ruminococcus sp. PO1-3 obtained from human intestinal flora is able to reduce dehydrocholate as well as 3-ketoglycyrrhetinate. From this bacterium dehydrocholate- and 3-ketoglycyrrhetinate-reducing activities were purified one thousand-fold together with 3-ketocholanate-reducing and 3-beta-hydroxyglycyrrhetinate (glycyrrhetic acid) oxidizing activities by means of
