Summary of immunolocalization studies of membrane transport proteins

Ref Transport Protein Technique Outcome
16 Sodium-potassium (NaKATPase) pump Immunohistochemistry Localized to the basal plasma membrane of epithelia cells. Most intense staining occurred in luminal cells layers
19 Epithelial sodium channels (ENaC) Immunohistochemistry Localized to the apical plasma membrane of epithelia cells. Most intense labeling occurred in luminal cell layers.
20 Cystic fibrosis transmembrane regulator (CFTR) chloride channels Immunohistochemistry Localized to the apical plasma membrane and cytoplasmic structures of epithelial cells. Most intense labeling occurred in luminal cell layers.
20 Sodium-potassium-chloride(Na+K+2Cl−) cotransporter Immunohistochemistry Localized to the apical and basolateral plasma membranes and cytoplasm of epithelial cells.
24 Aquaporin (AQP) water channels (AQP1, AQP2) Immunohistochemistry Localized to the apical plasma membrane and cytoplasmic structures of epithelial cells. Most intense labeling occurred in luminal cell layers.
