Product Description

7-Diethylamino-3-(4-maleimidophenyl)-4-methylcoumarin is a thiol-reactive fluorescent probe. CPM selectively forms Michael adducts in the presence of hyperreactive sulfhydryls. CPM has been used to monitor the release of thiols, quantitate thiol in microplate reactions, and to distinguish proliferating cancer cells by nucleolar protein staining. CPM displays excitation/emission maxima of 387/468 nm, respectively, and fluorescence intensity increases when bound to cysteine residues Synonyms: CPM, 1-[4-[7-(diethylamino)-4-methyl-2-oxo-2H-1-benzopyran-3-yl]phenyl]-1H-pyrrole-2,5-dione CAS No: 76877-33-3 Molecular Formula: C24H22N2O4 Molecular Weight: 402.44 Purity: 95% (HPLC) Appearance: Yellow solid Identity (1H-NMR): Conforms to structure Excitation: 384nm Emission: 470nm Solubility: Soluble in DMSO, DMF, Acetonitrile, Chloroform Storage and Stability: Lyophilized and reconstituted products are are stable for 6 months after receipt.
