Influence of pH on the proteolytic profile from pupae of Culex quinquefasciatus . The proteolytic activity was detected after incubation of gels in 100 mM sodium acetate (pH 3.5 or 5.5) or 100 mM Tris–HCl (pH 7.5 or 10.0), at 37°C for 12 h. The numbers on the right indicate approximate molecular masses of the peptidases, expressed in kDa.
