Product details:
Caspase-3 Assay Kit (Colorimetric) ab39401 allows the rapid, sensitive and accurate measurement of Caspase-3 activity in cell lysates.
How the assay works
The Caspase-3 assay protocol is based on the formation of the chromophore p-nitroaniline (p-NA) by cleavage from the labeled substrate DEVD-pNA. The p-NA can be quantified using a spectrophotometer or a microtiter plate reader reading absorbance at 400 or 405 nm.
Comparison of the absorbance of p-NA from an apoptotic sample with an uninduced control allows determination of the fold increase in Caspase-3 activity.
Caspase-3 Assay protocol summary
- Add samples to wells
- Add reaction buffer and DEVD-p-NA substrate and incubate for 60-120 min at 37°C
- Analyze with microplate reader
Note: Due to the nature of the substrate, this assay also detects caspase-7 activity.
