一般說明
Activation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. Chemicon′s Caspase-9 Colorimetric Activity Assay Kits provide a simple and convenient means for assaying the activity of caspases that recognize the LEHD. The assay is based on spectophotometric detection of the chromophore p-nitroaniline (pNA) after cleavage from the labeled substrate LEHD-pNA. The free pNA can be quantified using a spectrophotometer or a microtiter plate reader at 405 nm. Comparison of the absorbance of pNA from an apoptotic sample with an uninduced control allows determination of the fold increase in caspase-9 activity.

儲存和穩定性
Store kit materials at -20°C up to their expiration date.
Special Precautions:
· After thawing reagents, use immediately or aliquot and freeze at -20°C for longer storage. Avoid repeated freeze/thaw cycles.
· The Caspase-9 substrate and pNA standard are especially light sensitive. Maintain these reagents in amber or covered containers.
