Fig. 8. Immunohistochemistry of consecutive sections from the trailing edge region
of gills from sham-operated fish (A), acid-infused fish (B), and base-infused
fish (C). (Ai,Bi,Ci) Na+/K+-ATPase immunoreactivity;
(Aii,Bii,Cii) V-H+-ATPase immunoreactivity; (Aiii,Biii,Ciii)
diagrams of the approximate location of each immunostained cell. Cells that
labeled positive for Na+/K+-ATPase only are black, those
labeled for V-H+-ATPase only are white, and cells that labeled
positive for both transporters are gray. Scale bar, 10 µm.
