Product details:
Caspase-1 Assay Kit (Fluorometric) (ab39412) provides a simple and convenient method for detecting the activity of caspase-1, which recognizes the sequence YVAD.
The caspase-1 assay protocol is based on the cleavage of substrate YVAD-AFC (AFC: 7-amino-4-trifluoromethyl coumarin). YVAD-AFC emits blue light (Em=400 nm); upon cleavage of the substrate by caspase-1 or related caspases, free AFC emits a yellow-green fluorescence (Ex/Em=400/505 nm), which can be quantified using a fluorometer or a fluorecence microtiter plate reader. Comparison of the fluorescence from a treated sample with an untreated control allows determination of the fold increase in caspase-1 activity.
Caspase-1 assay protocol summary:
- add samples to wells
- add reaction buffer and YVAD-AFC substrate and incubate for 1-2 hr
- analyze with a microplate reader
Other Notes
Caspase-1 (ICE, IL-1beta Converting Enzyme) is the prototypical member of the ICE family of proteases/caspases.
