Fig. 1From: In-depth characterization of trypsin-like serine peptidases in the midgut of the sugar fed Culex quinquefasciatus Time course of proteolytic activities exhibited by midgut extracts of female C. quinquefasciatus fed on sugar. Proteolytic activities were evaluated after 2, 4, 6 and 12 h incubations in 0.1 M Tris–HCl buffer (pH 7.5). The numbers on the right indicate the molecular mass of standards utilized in the gel (kDa)Back to article page
