Ac-VEID-pNA, Colorimetric Substrate is a colorimetric substrate for caspase-6 (Km=30μM; Kcat/Km=168’000 M-1sec-1) and related cysteine proteases. The sequence is based on the lamin A site of cleavage. Cleavage of the substrate by a caspase results in the release of pNA, which can be detected by its absorbance at 405nm (ε=10,500 M-1cm-1).
