Caspase 8 Substrate 1, chromogenic

Caspase-8 substrate with Km = 66 uM; Substrate for granzyme B;
pNA (4-nitroaniline)-derived caspase substrates are widely used for the colorimetric detection of various caspase activities. Cleavage of pNA peptides by caspases generates pNA that is monitored colorimetrically at ~405 nm. pNA has maximum absorption around 408 nm.
