Caspase-2 Colorimetric Assay Kit

Activation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. The Caspase-2 Colorimetric Assay Kits provide a simple and convenient means for assaying the activity of caspases that recognize the sequence VDVAD. The assay is based on spectrophotometric detection of the chromophore p-nitroanilide (pNA) after cleavage from the labeled substrate VDVAD-pNA. The pNA light emission can be quantified using a spectrophotometer or a microtiter plate reader at 400- or 405 nm.
