Abstract
23Na NMR experiments with a suspension of the renal epithelial cell line, LLC-PK1/Cl4, in the presence of the shift reagent dysprosium polyphosphate showed that the intracellular sodium was only NMR visible for 64 +/- 4%. Intracellular sodium content was found to be 30.6 +/- 1.2 mM (25 degrees C). Examination of the sodium influx during recovery from intracellular acidification showed that sodium is transported not only by Na+/H+ exchange but also by sodium-D-glucose cotransport with a stoichiometry of 1:1.
