Potentiometric measurement of cell volume changes and intracellular ion concentrations in leech Retzius neurones

A potentiometric method to monitor cell volume changes in intact biological tissues is based on ion-selective microelectrodes filled with the classical K + exchanger Corning 477317, which is very sensitive to large quaternary ammonium ions. After introduction into a single cell, these cations can be...
