Product details:
Caspase-3 Assay Kit (Fluorometric) (ab39383) provides a simple and convenient means for assaying DEVD-dependent caspase activity.
Note: Due to the nature of the substrate, this assay also detects caspase-7 activity.
The Caspase-3 assay protocol is based on detection of cleavage of substrate DEVD-AFC (AFC: 7-amino-4-trifluoromethyl coumarin).
DEVD-AFC emits blue light (λ max = 400 nm). On cleavage of the substrate by CPP32 or related caspases, free AFC emits a yellow-green fluorescence (Ex/Em = 400/505 nm).
The signal can be quantified using a fluorometer or a fluorescence microtiter plate reader. Comparison of the fluorescence of AFC from an apoptotic sample with an uninduced control allows determination of the fold increase in Caspase-3/CPP32 activity.
Caspase-3 assay protocol summary:
- lyse cells / homogenize and lyse tissues in lysis buffer
- incubate on ice for 10 min
- add reaction buffer and DEVD-AFC substrate and incubate for 1-2 hr at 37°C
- analyze with fluorometer or microplate reader
