The properties of the Na-K pump and some of the factors controlling its amount and function were studied in rat myotubes in culture. The number of Na-K pump sites was quantified by measuring the amount of [3H]ouabain bound to whole-cell preparations. Activity of the pump was determined by measuremen
The aim of this study was to determine from macroscopic current analysis how intracellular magnesium ions, Mg { รท, interfere with sodium channels of mammalian neurones. It is reported here that permeation across the sodium channel is voltage-and concentrationdependently reduced by Mg 2+. This result
