WebFor example, several methods have been developed to detect S-nitrosated proteins separated by gel electrophoresis; they involve either a direct Western blotting detection with an anti-S-nitroso-cysteine (SNO-Cys) antibody or an indirect Western blotting detection using a biotin-switch technique (BST) [12, 16]. To detect chemically labile SNO ... WebSep 19, 2006 · The biotin-switch method was used to detect S-nitrosylation. After blocking cellular free thiols with N-ethylmaleimide, cells were MPB-labeled in the presence or absence of ascorbic acid to release NO. With specificity for high-Ca 2+ cells, immunoprecipitated PDI showed increased MPB labeling in the presence of ascorbic …
Webcontrol protein function. We have developed methods for the detec-tion and purification of proteins oxidized in this way. The method-ology is based on the arsenite-specific reduction of protein sulfenic acid under denaturing conditions and their subsequent labeling with biotin–maleimide.
