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。

After reconstitution in PBS, for how long is the protein stable in solution if stored at 4°C or -20*C?
1 answer-
Prepared BSA solution products also available for purchase. These products have a shelf life ranging from 18 months to 2 years. Many are assigned a restest schedule with no firm expiration date. These products are prepared in saline, DPBS, or Tris. These solutions are filtered products and offered in a range of concentrations. The storage recommendation for these products is 2 - 8 deg. C. In addition, BSA is often used as a carrier protein for less stable compounds that are stored frozen. While there is no established shelf life for a BSA solution stored frozen, it is quite stable. See the link below for a sample Certificate of Analysis for one of the BSA solutions.

Does this BSA have bovine immunoglobulins?
1 answer-
This product does contain bovine immunoglobulins. BSA products that do not contain immunoglobulins will state "globulin-free" or "essentially globulin-free" on the product detail page. Product A3156 is an example of an immunoglobulin free BSA product.

Is Product A7906, Albumin from bovine serum (BSA), protease-free?
1 answer-
We have not tested A7906 in quality control to be protease-free. Other BSA products to suggest that are protease-free would be A3059 or B6917.

Is Product A7906, Albumin from bovine serum (BSA), suitable for use as a blocking agent in ELISA?
1 answer-
We have not tested the use of A7906 in ELISA. Because the remainder of the product is mostly globulins, we would not suggest A7906 for ELISA use.

Can Product A7906, Albumin from bovine serum (BSA), be used in immunohistochemistry?
1 answer-
We have not ourselves tested A7906 for use in immunohistochemistry. However, a literature search can turn up publications that cite this use, such as this paper: Surendran, K., et al., Wnt-Dependent Beta-Catenin Signaling Is Activated after Unilateral Ureteral Obstruction, and Recombinant Secreted Frizzled-Related Protein 4 Alters the Progression of Renal Fibrosis. J. Am. Soc. Nephrol., Vol. 16, pp. 2373-2384 (2005).
