Biotin switch assay
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.
