Abstract
Isolated neuroblastoma cells (clone A-1 from clone N-18) were investigated by means of the intracellular dialysis technique. Changes in the ionic composition of intra- and extracellular media show that the fast inward current is carried by Na ions and delayed outward current is carried by K ions. Na inward current was blocked by TTX. Calcium inward current was not observed. Substitution of Na ions for K ions showed that PNa: PK = 7:1. A relatively low potassium conductance was found in the neuroblastoma cells.
