Cesium Chloride, Optical Grade is specifically prepared for use in density gradients. The highest grade commercially available, UltraPure™ Cesium Chloride, Optical Grade can be used to prepare plasmids or to isolate phage, virus particles, or cellular RNA.

Caesium chloride is widely used medicine structure in isopycnic centrifugation for separating various types of DNA. It is a reagent in analytical chemistry, where it is used to identify ions by the color and morphology of the precipitate.

Cesium chloride (CsCl), once a standard centrifugation medium for both analytical and preparative separation of nucleic acids, enjoys very limited use today. 

Custom Plasmid DNA Isolated by Double Cesium Chloride Ultracentrifugation Provides the Cleanest, Least Toxic DNA for Biological Studies. That Is, for Transformation or Transfection of Cells With Purified DNA, It Has Been Our Experience That Plasmid DNA Purified by This Method Exhibits the Least Amount of Cytotoxicity.
