Sodium-selective liquid ion-exchanger microelectrodes for intracellular measurements.

J O'Doherty et al.

Science (New York, N.Y.), 203(4387), 1349-1351 (1979-03-30)

The sodium-selective ligand 1,1,1-tris[1(1)-(2(1)-oxa-4(1)-oxo-5(1)-aza-5(1)-methyl)dodecanyl]propane dissolved in 3-nitro-o-xylene containing a small amount of the lipophilic anion tetrachlorophenyl borate was used as a liquid ion-exchanger in sodium-selective microelectrodes. The microelectrodes gave rapid, stable responses that were linear functions of the logarithm of
