Fig. 5. Western blot analysis for vacuolar-type proton pump (V-ATPase) protein
expressed in the gills of killifish adapted to a low-NaCl environment. The
membranes were incubated with anti-V-ATPase (lane B) and antibody
pre-incubated with the antigen (lane A). Positions of molecular markers (kDa)
are indicated on the left side of the figure. Two specific protein bands
(arrows) were obtained.
