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.

Figure 1. 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).
