Specific substrate for the determination of caspase-1 and caspase-1-like enzyme activities. Cleavage of this peptide substrate at the P1 Asp residue causes a continuous fluorescent assay, thus useful both in FACS and fluorescence microscopy experiments. Caspase-3 is only weakly active on this substrate. MW: 1431.48 Da. Purity >98 % purified
