Caspase-3 Substrate DEVD-pNA

Ready-to-use colorimetric substrate for CPP32/caspase-3 and related caspases that recognize the amino acid sequence DEVD. The sequence DEVD is based on caspase-3 cleavage site in poly (ADP-ribose) polymerase (PARP). CPP32 and related caspase activity can be quantified by spectrophotometric detection of free pNA (l = 400 nm) after cleavage from the peptide substrate DEVD-pNA, using a spectrophotometer or multi-well plate reader. The ready-to-use caspase substrate provides an economic alternative for researchers who perform large amounts of caspase assays.
