FITC-IETD-FMK

FITC-IE(OMe)TD(OMe)-FMK is a fluorescein isothiocyanate (FITC) conjugate of the cell- permeable caspase-8 inhibitor IE(OMe)TD(OMe)-FMK that acts as an in situ marker for detection of caspase-8 in living cells. FITC-IE(OMe)TD(OMe)-FMK is nontoxic, and irreversibly binds to activated caspase-8 in apoptotic cells. The bound marker is localized by fluorescence detection.
