Fluorescent Dyes  >  Enzyme Detection Reagents  >>  Caspase 8 Substrate 1, chromogenic

Product Name Caspase 8 Substrate 1, chromogenic
Ac - IETD - pNA
Size 5 mg
Catalog # AS-25258-5
US$ $108

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.

Caspase-8 substrate with Km = 66 uM; Substrate for granzyme B
