Description and Uses

Cesium chloride has been used in density gradient centrifugation and for fractionation of nucleic acids, ribosomal subunits, proteins, glycoproteins, and viruses. Cesium chloride can also be used as a raw material to prepare other cesium compounds, such as cesium chloride reacts with nitric acid and oxalate to prepare cesium carbonate. It can be applied to the discharge tube (positive ion provided by the filament surface) fluorescent screen and used as a contrast agent. It effectively prevents activation of caspase-3 and neuronal apoptosis in serum- and potassium-deprived cerebellar granule neurons by inactivating GSK-3β.
