Studies on the chemical modification of monensin. II. Measurement of sodium ion permeability of monensylamino acids using sodium-23 nuclear magnetic resonance spectroscopy.

Abstract

A technique to assay Na+ ions in cells is presented. Intracellular and extracellular Na+ ions in a suspension of guinea pig erythrocytes were conveniently determined by using sodium-23 nuclear magnetic resonance (23Na-NMR), in combination with two anionic shift reagents: Dy(TTHA)3- and Dy(PPPi)2(7-). Monensin (1), monensylalanine (2b), monensylserine (2c… (More)
