설명

일반 설명

Colorimetric substrate for CPP32/Apopain/Yama (K_m = 9.7 µM) and related cysteine proteases. Sequence is based on the P1-P4 tetrapeptide cleavage site of poly (ADP-ribose) polymerase (PARP) and includes Asp²¹⁶. CPP32 is the protease responsible for the cleavage of PARP. Can be used with Pro-caspase-3 in in vitro assays to measure caspase-9 activity, since caspase-9 activates pro-caspase-3. Cleavage of the substrate can be monitored at 405 nm (ε = 9160 cm^-1M^-1).

Colorimetric substrate for caspase-3 (K_m = 9.7 µM) and related cysteine proteases. Sequence is based on the P₁-P₄ tetrapeptide cleavage site of poly(ADP-ribose) polymerase (PARP) and includes Asp²¹⁶. Caspase-3 is the protease responsible for the cleavage of PARP. Also a substrate for caspase-6, caspase-7, caspase-8, and caspase-10. Cleavage of pNA is monitored colorimetrically at ~405 nm.
