Amplite® Fluorimetric Caspase 3/7 Assay Kit *Blue Fluorescence*

Amplite® Fluorimetric Caspase 3/7 Assay Kit

Blue Fluorescence

Caspases play important roles in apoptosis and cell signaling. The activation of caspase-3 (CPP32/apopain) is important for the initiation of apoptosis. Caspase 3 is also identified as a drug-screening target. Caspase 3 has substrate selectivity for the peptide sequence Asp-Glu-Val-Asp (DEVD). This Amplite® Caspase-3 Assay Kit uses Ac-DEVD-AMC as fluorogenic indicator for assaying caspase-3 activity. AMC-derived caspase substrates are widely used for fluorimetric detection of various caspase activities. Cleavage of AMC peptides by caspases generates strongly fluorescent AMC that is monitored fluorimetrically at 440-460 nm with excitation of 340-350 nm. This kit can be used to continuously measure the activities of caspase-3 in cell extracts and purified enzyme preparations using a fluorescence microplate reader or fluorometer.

Detection of Caspase 3/7 activity in Jurkat cells with Cell Meter™ Caspase 3/7 Activity Apoptosis Assay Kit. Jurkat cells were seeded on the same day at 80,000 cells/well/90 µL in a Costar black wall/clear bottom 96-well plate. The cells were treated with or without 1 µM of staurosporine for 4 hours, and with or without 10 µM of the caspase inhibitor AC-DEVD-CHO for 10 minutes. The caspase 3/7 assay solution (100 µL/well) was added and incubated at room temperature for 1 hour. The fluorescence intensity was measured at Ex/Em = 350/450 nm (Cutoff = 420 nm).
