General description

7-Diethylamino-3-(4-maleimidophenyl)-4-methylcoumarin (CPM), is a highly fluorescent, sulfhydryl (-SH) group containing coumarin derivative. It has excitation an emission wavelengths of 355 and 460 nm, respectively.[1]

Application

7-Diethylamino-3-(4-maleimidophenyl)-4-methylcoumarin has been used:
  • as a nontoxic substitute for conjugation with antibody(93)
  • to aid fluorescent detection of Coenzyme A (CoA-SH) in human N-myristoyltransferases assay (94)
  • in thermostability shift assay of recombinant protein(95)

Biochem/physiol Actions

Used to monitor release of thiols, quantitate thiol in microplate reactions, and to distinguish proliferating cancer cells by nucleolar protein staining.
