Fig. 3. Max projection images of immunolocalized transport proteins in the alimentary canal of larval An. gambiae. (A,B) The localization of AgNHA1 (red) and H⁺ V-ATPase (red), respectively. (C) The colocalization of AgNHA1 (red) with Na⁺/K⁺-ATPase (green). (D) The colocalization of H⁺ V-ATPase (red) with Na⁺/K⁺ P-ATPase (green). Ventral view of the alimentary canal so DAR cells are not visible. The yellow color in C,D results from the colocalization of AgNHA1 and H⁺ V-ATPase (both red) with Na⁺/K⁺ P-ATPase (green).
