Caspase-8 Fluorometric Assay Kit

Activation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. The FLICE/Caspase-8 Fluorometric Assay Kits provide a simple and convenient means for assaying the activity of caspases that recognize the sequence IETD. The assay is based on detection of cleavage of substrate IETD-AFC (AFC: 7-amino-4-trifluoromethyl coumarin). IETD-AFC emits blue light (λmax = 400 nm); upon cleavage of the substrate by FLICE or related caspases, free AFC emits a yellow-green fluorescence (λmax = 505 nm), which can be quantified using a fluorometer or a fluorecence microtiter plate reader.
