Immunofluorescence microscopy of NaPi-2b protein in intestinal sections corresponding to rat jejunum (30–50 cm). Abundance of NaPi-2b protein is increased in apical membrane of enterocytes in rats chronically fed low-Pi diet. Sections were embedded in optimal cutting temperature compound, fixed with methanol, and stained with anti-NaPi-2b antibody.
