DescriptionSubstrate for fluorogenic assay of plasma and glandular kallikreins. Also serves as a substrate for cathepsin B, cathepsin L, and papain.
FormWhite to off-white solid
Recommended reaction conditions
Protocol for the Assay of Cathepsin L Enzyme: Cathepsin L is one of the lysosomal cysteine proteinases involved in the turnover of endocytosed proteins. It also has a higher specific activity towards physiological substrates, such as collagen and fibronectin over other lysosomal enzymes. It has an acidic optimal pH of 5.5. It is rapidly inactivated, 85% loss of activity in ~15 min, at pH 7.0-7.4. Substrate: Z-Phe-Arg-7-amido-4-methylcoumarin is more sensitive to cathepsin L than cathepsin B, although both enzymes will cleave the substrate. To determine cathepsin L activity, the specific cathepsin B substrate, Z-Arg-Arg-7-amido-4-methylcoumarin (Cat. No. 03-32-1570), can be used. The substrate is non-fluorescent, but when hydrolyzed by the enzyme it releases highly fluorescent 7-amido-4-methylcoumarin (AMC). AMC can be quantitated with a spectrofluorometer using an excitation at ~370 nm and an emission at ~460 nm. Reagents: • Assay/Activator: 340 mM sodium acetate, 60 mM acetic acid, and 4 mM EDTA, Buffer pH 5.5; add DTT to a final concentration of 8 mM just prior to use. • Substrate: Prepare a 1 mM Z-Phe-Arg-7-amido-4-methylcoumarin stock solution in DMSO and store in a -20°C freezer. Dilute to 20 µM with H2O prior to use. • Stop Solution: 100 mM sodium monochloroacetate, 70 mM acetic acid, and 30 mM sodium acetate, pH 4.3 • Diluent: BRIJ® 35 (0.1% in H2O) • Standard: Prepare a 1 mM AMC stock solution in DMSO and store in a 4°C refrigerator. Dilutions are made using a 1:1 mixture of Assay Buffer and Stop Solution. Procedure: 1. Using the Diluent, prepare 500 µl of enzyme sample in 5 ml glass or polystyrene tubes. 2. Add 250 µl of assay/activator buffer. Allow ~1 min. incubation at 30°C for temperature equilibration and enzyme activation. Note: longer incubation may result in loss of activity. 3. Add 250 µl of the 20 µM substrate solution and mix. 4. Following a 10 min incubation at 30°C, add 1 ml of Stop Solution. 5. Measure the fluorescence and determine the molar amount using a standard curve for AMC. The fluorescence of AMC is only minimally affected by pH in the range of 4-7.
