Caspase 4, also known as Ich-2(ICE and CED-3 homolog 2), also known as TX and ICErel-II, can interact with Apaf-1 and participate in caspase 3 activation caused by cytochrome c. Caspase 4 can also interact with caspase 14. This caspase 4 activity assay kit is based on caspase 4 that can catalyze the substrate Ac-LEVD-pNA to generate yellow pNA (p-Nitroaniline). The pNA has a strong absorption near 405 nm, The activity of caspase 4 can be calculated by determining the absorbance at 405 nm.
