FITC-DEVD-FMK(ab285397)

MW 923.91 g/mol, Purity >98%. A fluorescein isothiocyanate (FITC) conjugate of the cell-permeable caspase inhibitor D(OMe)E(OMe)VD(OMe)-FMK that acts as an in situ marker for detection of caspase-3 in living cells. FITC-D(OMe)E(OMe)VD(OMe)-FMK is nontoxic, and irreversibly binds to activated caspase-3 in apoptotic cells. The bound marker is localized by fluorescence detection.
