Description_x000D_ General description_x000D_ 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._x000D_ Application_x000D_ Cesium methanesulfonate has been used as a supplement in intracellular solution for the patch clamp recording system._x000D_ Packaging_x000D_ 5, 25 g in glass bottle
