Fig. 5. Immunolocalization of transport proteins in longitudinal sections of
mosquito alimentary canal from various regions. H+ V-ATPase (red)
and Na+/K+ P-ATPase (green) antibodies labeled sections
of the gastric caeca (GC; A), anterior midgut (AMG; B), posterior midgut (PMG;
C,D), a Malpighian tubule (MT; white arrow in D) and rectum (G). The apical
membrane of posterior midgut region is labeled with AgNHA1 antibody (red; E)
and a nutrient amino acid transporter, AgNAT8 antibody (red; F). The yellow
color in A,D,G results from the colocalization of H+ V-ATPase (red)
with Na+/K+ P-ATPase (green). The nuclei are labeled
blue with DRAQ. Scale bar, 100 µm.
