Immunofluorescence staining using antibody against the Na⁺/K⁺-ATPase in sections of rat kidney OSOM. Magnification 600×. Tubular epithelial cells of outer stripe of the outer medulla (OSOM) were labeled by indirect immunofluorescence under control, LP, and RP conditions. In control OSOM, basolateral Na⁺/K⁺-ATPase expression was present. After LP, dislocation of Na⁺/K⁺-ATPase from basolateral domain into apical domain was shown. A pattern of basolateral Na⁺/K⁺-ATPase distribution during RP similar to control was shown
