Figure 9From: Proteolytic profiling and comparative analyses of active trypsin-like serine peptidases in preimaginal stages of Culex quinquefasciatusDetection of proteolytic activity from the four larval instars of Culex quinquefasciatus using the fluorogenic substrate Z-Phe-Arg-AMC. The proteolytic assays were performed in the absence (control) or presence of 100 μM TLCK in 100 mM sodium phosphate (pH 7.5).Back to article page
