General 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.

Application

Cesium methanesulfonate has been used as a supplement in intracellular solution for the patch clamp recording system.

Endocannabinoid signaling in the dorsal raphe (DR) has recently been implicated in the regulation of anxiety and depression. However, the cellular mechanisms by which endocannabinoids (eCBs) regulate the excitability of DR 5-hydroxytryptamine (serotonin; 5-HT) neurons remain poorly understood. In the
