Caspase 8 (active) FITC Staining Kit (ab65614) provides a convenient means for sensitive detection of activated caspase 8 in living cells. The assay utilizes the caspase 8 inhibitor, IETD-FMK, conjugated to FITC (FITC-IETD-FMK) as a marker. FITC-IETD-FMK is cell permeable, non-toxic, and irreversibly binds to activated caspase 8 in apoptotic cells. The FITC label allows detection of activated caspase-8 in apoptotic cells directly by fluorescence microscopy, flow cytometry, or fluorescence plate reader.

Activation of caspases plays a central role in apoptosis.
|FITC-IETD-FMK||1 x 100µl|
