Ac-IETD-pNA is a substrate for caspase-8 and granzyme B. Caspase 8 is a cysteine protease involved in apoptosis induced by Fas and other stimuli. It is an attractive therapeutic target for a variety of degenerative disorders. Granzyme B is a serine protease found in cytotoxic T-cells and NK cells. It cleaves and activates a number of caspases involved in apoptosis.

Activity is quantified by the release of p-nitroaniline which is measured by absorbance at 405 nm.
