Z-Asp-Glu-Val-Asp-AFC

Caspase 3, a cysteine protease activator of caspase 6 and caspase 7, metabolizes amyloid-β 4A precursor protein. Caspase 3 may be detected using a variety of chromogenic and fluorogenic peptide substrates built around the DxxD (asp-x-x-asp) sequences DMQD and DEVD such as Ac-DMQD-pNa (Acetyl-Asp-Met-Gln-Asp-p- nitroanalide), chromogenic; Ac-DMQD-AMC (Acetyl-Asp-Met-Gln-Asp-amino-4-methylcoumarin), fluorogenic; Z-DEVD-AFC (Z-Asp-Glu-Val-Asp-AFC), flourogenic and Ac-DEVD-4M2Na.
