Kallikrein activity assay. Cleavage of kallikrein substrate (H-D-Pro-Phe-Arg-pNa) by living schistosomes (triangle) and human kallikrein (0.02 μg) in the presence (square) or absence (circle) of PMSF (2 mM) (Mean +/- SD, n = 3). Released pNa was measured every 5 minutes at OD405. All conditions differ significantly from “Kallikrein”; two-way ANOVA: F(24,52) = 94.76, F(2,52) = 2318.22, F(12,52) = 124.82, P < 0.0001
