Description

Application

The Caspase 3 Fluorimetric Assay Kit is designed for the detection and measurement of caspase 3 activity in cell extracts or purified preparations of caspase 3.

Unit Definition

One unit of caspase 3 will cleave 1.0 μmol of Ac-DEVD per min at pH 7.4 at 25 °C.

General description

The Caspase 3 Fluorometric Assay Kit is based on the hydrolysis of acetyl Asp-Glu-Val-Asp 7-amido-4-methylcoumarin (Ac-DEVD-AMC) by caspase 3, resulting in the release of the fluorescent 7-amino-4-methylcoumarin (AMC). The excitation and emission wavelengths of AMC are 360 nm and 460 nm respectively. The concentration of the AMC released can be calculated from a calibration curve prepared with AMC standards (AMC standard included with the kit).
