一般說明
Bovine Serum Albumin (BSA) is a globular and α-helical single-chain protein, produced in the liver. This non-glycosylated protein belongs to the serum albumins family. BSA consists of three homologous domains with two sub-domains each.
應用
Bovine Serum Albumin (BSA) has been used:
- as a standard protein in the elution-filter aided proteome preparation (FASP) method and in sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)
- as a component of the molecular weight marker in SDS-PAGE and western blotting
- as a blocking agent in immunofluorescence
生化／生理作用
BSA的某些构象和初级序列表位是人类对牛肉和牛奶过敏中的可疑过敏原。
Bovine Serum Albumin (BSA) participates in the transport of endogenous and exogenous substances, such as hormones, fatty acids, drugs, and xenobiotics. It is used as a blocking agent in enzyme-linked immunosorbent assay (ELISA). BSA is usually preferred for the preparation of serum-free media. It is used in the pharmaceutical and cosmetic industry.
準備報告
血清白蛋白可能也会被称为Fraction V。该命名惯例取自使用冷乙醇沉淀对血清蛋白进行分级的原始Cohn法。 血清白蛋白可在采用Cohn′法的第五乙醇分级中发现。 从此，有些人便开始使用“Fraction V”这一术语来描述血清白蛋白，无论使用的是什么制备方法。 也有人在使用该术语来描述通过乙醇分级方法而纯化得到血清白蛋白，而这种方法是相对于原始的Cohn法一直在得到高度的改良。Sigma-Aldrich生产和分销从各种主要方法纯化得到的血清白蛋白，包括真正的Cohn分级法、改良的乙醇分级方法、热休克和色谱法。 更多的纯化步骤包括结晶或木炭过滤。

Currently, the separation targets of preparative electrophoresis range from milligrams to micrograms of proteins. However, most commercially available preparative electrophoretic instruments function at the milligram level. Although some preparative electrophoretic apparatuses operated at the microgram level, the fractionation results are
