How the assay works
Cathepsin B Activity Assay Kit (Fluorometric) utilizes the
preferred cathepsin-B substrate sequence RR labeled with AFC
(amino-4-trifluoromethyl coumarin).
Cell lysates or other samples that contain cathepsin-B will
cleave the synthetic substrate RR-AFC to release free AFC. The released AFC can
easily be quantified using a fluorometer or fluorescence plate reader at Ex/Em
400/505 nm.
Cathepsin B Activity Assay Kit protocol summary:
- Prepare samples
- Add Cathepsin B Reaction Buffer/reaction buffer
- Add Ac-RR-AFC substrate
- Incubate for 1 -2 hours at 37°C
- Measure fluorescence (Ex/Em = 400/505 nm)
