Fig. 2From: Expression of active trypsin-like serine peptidases in the midgut of sugar-feeding female Anopheles aquasalis Effect of pH on the proteolytic profiles of the midgut of An. aquasalis female. Enzymatic activities were evaluated after incubating the gels for 2 h at 37 °C in reaction buffer containing 100 mM sodium acetate at pH 3.5 or 5.5 or 100 mM Tris–HCl at pH 7.5 or 10.0. The numbers on the left indicate the apparent molecular masses of the active bands expressed in kDaBack to article page
