The Caspase-Glo 3/7 Assay provides a homogeneous luminescent assay that measures caspase-3/7 activities. The assay provides a proluminescent caspase-3/7 DEVD-aminoluciferin substrate and a proprietary thermostable luciferase in a reagent optimized for caspase-3/7 activity, luciferase activity and cell lysis. Adding the single Caspase-Glo 3/7 Reagent in an add-mix-measure format results in cell lysis, followed by caspase cleavage of the substrate. This liberates free aminoluciferin, which is consumed by the luciferase, generating a glow-type luminescent signal. The signal is proportional to caspase-3/7 activity. The stabilized luciferase and proprietary buffer system improve assay performance across a wide range of assay conditions, and the assay is less likely to be affected by compound interference unlike fluorescent- or colorimetric-based assays. The Caspase-Glo 3/7 Assay is designed for use with multiwell plate formats using either purified enzyme or cells in culture.
