Caspase-3 Colorimetric Assay Kit
Description
This Caspase-3 Colorimetric Assay Kit is designed to detect caspase-3(an early marker of cells undergoing apoptosis) or DEVD-cleaving activity, and determine if certain apoptosis pathways involve caspase-3 activation. The kit contains a caspase-3 fluorogenic substrate (Ac-DEVD-pNA) and assay buffers. The assay is based on spectrophotometric detection of the chromophore p-nitroanilide (pNA) after cleavage from
the labeled substrate DEVD-pNA. The pNA light emission can be quantified using a spectrophotometer or a microtiter plate reader at 400- or 405-nm. Comparison of the absorbance of pNA from an apoptotic sample with an uninduced control allows determination of the fold increase in Caspase 3 activity.
