Activation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. The Caspase-9 Colorimetric Assay Kit provides a simple and convenient means for assaying the activity of caspases that recognize the sequence LEHD. The assay is based on spectrophotometric detection of the chromophore p-nitroanilide (pNA) after cleavage from the labeled substrate LEHD-pNA. The pNA light emission can be quantified using a spectrophotometer or a microtiter plate reader at 400- or 405-nm.

‧ Detection method- Spectrophotometer (OD-400- or 405-nm) or a microtiter plate reader
‧ Sample type- Cell and tissue lysates
‧ Species reactivity- Mammalian
‧ Applications- Detect early/middle stages of apoptosis; differentiate apoptosis from necrosis.

Features and Benefits
‧ Simple one-step procedure; takes 1-2 hours
‧ Fast and convenient
‧ Comparison of the absorbance of pNA from an apoptotic sample with an uninduced control allows determination of the fold increase in Caspase-9 activity.
