Our Cell Meter™ live cell caspases activity assay kits are based on fluorescent FMK inhibitors of caspases. These inhibitors are cell permeable and non-cytotoxic. Once inside the cell, the caspase inhibitors bind covalently to the active caspases. This Cell Meter™ Live Cell Caspase 8 Activity Assay Kit is designed to detect cell apoptosis by measuring caspase 8 activation in live cells. It is used for the quantification of activated caspase 8 activities in apoptotic cells, or for screening caspase 8 inhibitors. iFluor 647-LETD-FMK, the red label reagent, allows for direct detection of activated caspase 8 in apoptotic cells by fluorescence microscopy, flow cytometer, or fluorescent microplate reader. The kit provides all the essential components with an optimized assay protocol.
Flow cytometric analysis of active caspase 8 using Cell Meter™ Live Cells Caspase 8 detection kit in Jurkat cells. The cells were treated with 1 μM staurosporine for 5 hours (Green) while untreated cells were used as a control (Red). The staurosporine response was inhibited by Z-VAD-FMK (caspase inhibitor) shown as blue. Cells were incubated with iFluor 647-LETD-FMK for 1 hour at RT. The fluorescent intensity was measured using NovoCyte flow cytometer with 660/20 nm filter (APC channel).
