CPM, Thiol-reactive fluorescent probe(AB145275)

MW 402.44 g/mol, Purity >95%. Widely used blue fluorescent thiol-reactive dye. Essentially non-fluorescent until it reacts with thiols, making it possible to quantify thiols without a separation step. Good energy acceptor from tryptophan and a good energy donor to fluorescein. Used to monitor release of thiols and to distinguish proliferating cancer cells by nucleolar protein staining.
