Mouse anti-Nitroso-cysteine monoclonal antibody for ICC, IHC, WB. All mammalian cellscontain low levels of nitrosylated proteins, that are thought to be regulatedby Snitrosylation and denitrosylation. S nitrosylation of proteins serves asa ubiquitous post-translational modification that dynamically regulates abroad functional spectrum of proteins. The majority of these proteins areregulated by S nitrosylation on a single critical cysteine residue within anacidic/basic or hydrophobic structural motif, that may also be subject tooxygen or glutathione dependent modification, suggesting that S nitrosylationis a prototypic redox signal.
