Caspase Colorimetric and Fluorescent Assay Kits

The ApoAlert Caspase Assay Kits provide a simple and convenient way to detect caspase protease activity using fluorometric or colorimetric methods. The assay kits detect caspase activation by assaying for the cleavage of a fluorescent or a colorimetric substrate. The entire protocol—from collection of cells to fluorometric or colorimetric results—takes only 90 minutes.

Caspase Colorimetric Assay Kits & Caspase Fluorescent Assay Kits

The Caspase-3 Colorimetric Assays measure the proteolytic cleavage of the chromophore p-nitroanilide (pNA) by caspase-3. Liberated pNA can be monitored colorimetrically by absorbance at 405 nm.

The Caspase-9/6 Fluorescent Assay detects the shift in fluorescence of 7- amino-4-methoxy coumarin (AMC). Upon cleavage, AMC fluorescence can be measured using a 380-nm excitation filter and a 460-nm emission filter. Fluorescence detection is highly sensitive and can be used to measure even very small amounts of active caspase.

The Caspase-3 Fluorescent Assays detect the shift in fluorescence emission of 7-amino-4-trifluoromethyl coumarin (AFC). After the substrate is cleaved by the protease, AFC emits a yellow-green fluorescence at 505 nm if excited at 400 nm.
