Serine Protease Assay Kit
Fluorescent Labeled Inhibitors of Serine Protease (FLISP) kits allow the analysis of intracellular chymotrypsin-like serine protease activity in live cells. Serine protease activation plays major roles in several different cellular functions including apoptosis, tumor malignancy and as diagnostic and prognostic indicators of breast, head and neck carcinomas. Serine proteases are also thought to play a role in infections and transplant rejection.
Product Details

Propidium Iodide, 1 mL
Hoechst Stain, 1 mL - Test Principle
- Active chymotrypsin-like enzymes within the cell bind covalently to the FLISP FAM-Phe-DAP inhibitor probe, retaining the green fluorescent signal within the cell. The higher the concentration of active chymotrypsin-like enzymes within the cell, the higher the level of fluorescence observed. FLISP kits are suitable for use with suspension or adherent cells and can be used with a flow cytometer, fluorescence microscope or a fluorescence plate reader.
FLISP inhibitors are cell-permeable and non-cytotoxic fluorochrome-labeled analogs of the first serine protease inhibitor, tosyl-phenlalanylchloromethyl ketone (TPCK), labeled with carboxyfluorescein (FAM) which fluoresces green. They are available with either a chloromethyl ketone (CMK) or diphenyl 1-(N-peptidylamino) alkanephosphonate (DAP) reactive group containing compound. Specificity for chymotrypsin-like enzymes is determined by the amino acid targeting peptide, the FAM-Phe-DAP probe inhibits chymotrypsin.
