  • Title: Amiloride-inhibited Na+ uptake into toad bladder microsomes is Na+-H+ exchange.
    Author: LaBelle EF, Eaton DC.
    Journal: Biochim Biophys Acta; 1983 Aug 24; 733(1):194-7. PubMed ID: 6309226.
    Abstract:
    Amiloride-inhibited Na+ transport into toad urinary bladder microsomes is sensitive to a pH gradient across the vesicular membrane. The magnitude of the gradient was measured directly with acridine orange. Also Na+ could stimulate amiloride-sensitive proton efflux from the microsomes. These results indicated that the transport process was Na+-H+ exchange.
