Description

Cesium methanesulfonate is used as a component of intracellular recording solutions of electrodes for patch clamp techniques in cell electrophysiology studies.Cesium methanesulfonate is used as an current carrier as cesium acts as a potassium (K+) channel blocker,while methanesulfonate is not transported through chloride (Cl-) channels.
