General description

Cesium chloride is a cesium halide. Cesium halides can be prepared by reacting cesium carbonate with corresponding hydrohalic acids.[1] Cesium chloride ultracentrifugation method has been reported for the extraction of RNA from cellular fractions.[2]

Application

Cesium chloride may be employed in gel-electrophoresis† and RNA purification studies.† It may be employed for the isolation of bacterial plasmid from Agrobacterium spp.†
Used for the preparation of electrically conducting glasses.Used to make solutions for the separation of RNA from DNA by density gradient centrifugation.
