Biotin switch method
WebApr 1, 2005 · The so-called biotin-switch method has been developed to identify S-nitrosated proteins. This method relies on the selective reduction of S-nitrosothiols by ascorbate. In this study we have assessed the ability of ascorbate to reduce S-nitrosothiols and show that ascorbate is a very inefficient reducing agent. We show that higher … WebJan 1, 2014 · The biotin-switch method was pioneered by Jaffrey and Snyder in 2001 [47], and further developed by others [22].
