Ac-DEVD-AFC (CAS 201608-14-2)

Ac-DEVD-AFC is a fluorogenic substrate for caspase-3 (CPP32) and related cysteine proteases, which emits a blue to green shift in fluorescence. It also acts as a substrate for granzyme B-processed caspase-6, caspase-7, caspase-8, and caspase-10. It is known that Ac-DEVD-AFC has a greater Stokes' shift than Ac-DEVD-AMC once it has been cleaved. Since caspase-3 is an effector caspase, it is involved in the cleavage of many substrates which promote apoptosis. This indicator excites light at 400nm and emits light at 505 nm. In addition, Ac-DEVD-AFC is modeled after Asp216 on caspase-3, the PARP cleavage site. Ac-DEVD-AFC is an essential indicator used to monitor the cellular effects of caspase-3.
