9689c5aa-6556-4b3c-b5d1-1e693715ba07 developed CPMTS as an alternative to the widely used thiol-reactive coumarin dye CPM. CPMTS and CPM have nearly identical absorption and emission spectra. However, CPMTS contains a MTS group, which could make the dye more advantageous than CPM for sulfhydryl labeling because of the high selectivity and reactivity of MTS reagents toward thiol groups.
