Fig. 5. Immunolocalization of the AaeCG12773 cotransporter in the mosquito
digestive system. (A) The gut and Malpighian tubules of a 4th instar larva of
Aedes aegypti. Specific immunostaining is detected in gastric ceca
(CA), anterior (AMG) and posterior (PMG) midgut and pylorus (P).
Immunofluorescence in the Malpighian tubules (MT) and rectum (R) is low and
does not exceed background levels of pre-immune serum. (B,C)
Immunohistochemistry of sections of a 4th instar A. aegypti larva.
Subcellular localization of the AaeCG12773 cotransporter by specific
antibodies clearly shows that it is predominantly present in the basolateral
membrane of the midgut. No specific immunoreactivity was observed in sectioned
Malpighian tubules and rectum.
