Protease Substrates

TEV protease kit that may be used for cleaving proteins or peptides containing the TEV protease recognition sequence E-N-L-Y-F-Q↓(S/G/A/M/C/H).

A fluorogenic substrate for caspase-3 that can be used to continuously measure the activity of caspase-3 in cell extracts, using a fluorometer or fluorescence microplate reader.

Fluorescent caspase-3/7 substrates for detecting apoptosis in intact cells by confocal microscopy, flow cytometry, or live cell imaging.

Homogeneous, no wash assay for detection of caspase-3/7 activity with green fluorescence and dead cell staining with far-red fluorescence, for fluorescence microscopy or flow cytometry.

Z-AA-R110-PEG (Rhodamine 110-PEG, N-CBZ-L-alanyl-L-alanine amide) is a substrate for elastate.

BZiPAR (Rhodamine 110, bis-(N-CBZ-L-isoleucyl-L-prolyl-L-arginine amide), dihydrochloride) is a substrate for trypsin (1,2). The substrate has been reported to enter live cells and be hydrolyzed by lysosomal proteases (3).

Z-FR-R110 (Rhodamine 110, bis-(N-CBZ-L-phenylalanyl-L-arginine amide), dihydrochloride) is a substrate for the cysteine proteases cathepsins B and L. The substrate has been used in flow cytometry studies of human monocytes and rat macrophages.

Ac-DEVD-AMC is a fluorogenic substrate for caspase 3 and can be used to continuously measure the activity of caspase-3 in cell extracts, using a fluorometer or fluorescence microplate reader. For real-time detection of caspase-3 activity in intact cells, see our novel NucView®488 Caspase-3 Assay Kit.

BZAR (Rhodamine 110, bis-(N-CBZ-L-arginine amide), dihydrochloride) is a substrate for serine proteases (1-5) and is also an inhibitor for quanidinobenzoatase. It is 50 to 100 times more sensitive than the AMC-based substrate.

Z-FR-AMC is a substrate for serine proteases, including cathepsins, kallikrein and plasmin.

Rhodamine 110 can be used as a reference standard for rhodamine 110-based peptidase substrates.

No wash, homogeneous assay for profiling apoptotic cells based on caspase-3 activity and changes in the mitochondrial membrane potential using fluorescence microscopy, real-time imaging, or flow cytometry.

Green fluorescent caspase-3/7 substrate for detecting apoptosis in intact cells by confocal microscopy, flow cytometry, or real-time live cell imaging.

A fluorometric endpoint assay kit for detection of caspase-3 activity in cells by high throughput screening (HTS).

Z-AAD-R110 is a substrate for granzyme B. Granzyme B from T lymphocytes and natural killer cells induces apoptosis in target cells by activating caspases and causing mitochondrial cytochrome C release.

R110-PEG can be used as a reference standard for peptidase substrates based on the dye.
