Ion-selective microelectrodes are a powerful tool in studying adaptive responses of plant cells and tissues to various abiotic stresses. However, application of this technique in Na(+) flux measurements was limited due to poor selectivity for Na(+) ions of commercially available

We investigated the Na-dependent Ca transport in purified bovine luminal and basolateral renal tubular membranes. Na-dependent Ca uptake was observed in basolateral but not in luminal kidney tubular membranes. 45Ca uptake in basolateral membrane vesicles loaded with Na and suspended

The high background K+ concentration in plant cells is a problem for intracellular measurements of Na+ using ion-selective microelectrodes. The discrimination between Na+ and K+ of the microelectrode ionophore molecule limits the usefulness of this technique. A new Na+-selective microelectrode

The Journal of membrane biology, 139(2), 117-125 (1994-04-01)
Na(+)-selective microelectrodes with the sensor ETH 227 have been used to measure the cytoplasmic Na+ concentration, [Na+]c, in Acetabularia. In the steady-state, [Na+]c is about 60 mM (external 460 mM). Steps in external Na+ concentration, [Na+]o, cause biexponential relaxations of
