Description and Uses
7-Diethylamino-3-(4-maleimidophenyl)-4-methylcoumarin is a thiol-reactive fluorescent probe. It displays excitation/emission maxima of 387/468 nm, respectively, and fluorescence intensity increases when bound to cysteine residues.
(7-Diethylamino-3-(4'-maleimidylphenyl)-4- methylcoumarin)CPM is probably the most widely used blue fluorescent thiol-reactive dye. This maleimide derivative of coumarin is essentially nonfluorescent until it reacts with thiols, making it possible to quantify thiols without a separation step. CPM is a good energ
