This product is prepared by heat-shock fractionation which tends to yield a higher purity of Fraction V Albumin. The product is not tested for the presence of globulins or fatty acids on a lot-to-lot basis. However, historical information indicates the presence of fatty acids with low to no IgG detected. Alpha-globulin has been detected in the past.

制备说明
热激分级分离法制取
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。

The signal sequence is not determined for Bovine Serum Albumin products. The signal/target sequence for BSA is most often associated with the preproalbumin in vivo. See the link below, section 3.1, for further information.
