pGlu-Pro-Arg-MNA [N-(3-[2-Furyl]-acryloyl) - L - leucyl - glycyl - p - nitroanilide] is a chromogenic peptide substrate, specifically utilized for its role in biochemical assays.
pGlu-Pro-Arg-MNA monoacetate, a thrombin substrate modeled after a thrombin cleavage site in human fibrinogen, can be used for sensitive assays of antithrombin III activity.
