[Comparative analysis of the characteristics of potassium channels in the membranes of spinal ganglion neurons and neuroblastoma cells].
The method of intracellular perfusion and voltage clamp was used to investigate potassium channels in the somatic membrane of the rat spinal ganglion neurons and mouse neuroblastoma cell. It is shown that potential-dependent properties of potassium channels in both types of membranes are similar while time constants of activation and inactivation are substantially higher in the neuroblastoma cells. The density of potassium channels was ten times less in the neuroblastoma cells than in the spinal ganglion neurons.
