Fig. 4From: Characterization of a secreted cystatin of the parasitic nematode Haemonchus contortus and its immune-modulatory effect on goat monocytesInhibition of protease activities by the recombinant protein of HCcyst-3. Cathepsin L, cathepsin B, papain and caspase 1 were incubated with each of the substrates in the presence of different concentrations of rHCcyst-3. Incubation of proteases without rHCcyst-3 resulted in 100% enzyme activityBack to article page
