Figure 6From: Proteolytic profiling and comparative analyses of active trypsin-like serine peptidases in preimaginal stages of Culex quinquefasciatusTime course of proteolytic activity from pupae of Culex quinquefasciatus . Enzyme activity was detected after incubation for 2, 4, 6, 12 or 24 h at 37°C in 100 mM Tris–HCl (pH 7.5). The numbers on the right indicate the apparent molecular masses of the peptidases, expressed in kDa.Back to article page
