CPM

Abstract

CPM Description Thiol-reactive fluorescent probe. Biological description 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. Purity > 95%
