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 1 Activity Assay Kit is designed to detect cell apoptosis by measuring caspase 1 activation in live cells· It is used for the quantification of activated caspase 1 activities in apoptotic cells, or for screening caspase 1 inhibitors· FAM-YVAD-FMK, the green label reagent, allows for direct detection of activated caspase 1 in apoptotic cells by fluorescence microscopy, flow cytometer, or fluorescent microplate reader· The kit provides all the essential components with an optimized assay protocol·
