WebS-nitrosylation (or S-nitrosation, SNO) is an oxidative posttranslational modification to the thiol group of a cysteine amino acid residue. There are several methods to detect SNO modifications, mostly based on the classic biotin-switch assay, where the labile SNO sites are replaced with a stable biotin moiety to facilitate enrichment of the modified proteins. WebFeb 21, 2012 · The biotin switch assay followed by Western blot or immunoprecipitation using an S-nitrosocysteine antibody was also employed to validate S-nitrosylated proteins in endothelial cell lysates. Results Seventy-eight potential S-nitrosylated proteins and their target cysteine residues for S-nitrosylation were identified; 9 of them were Golgi ...
