14.1.4.2.2 Cesium Chloride Density Gradient Method. Cesium chloride (CsCl) is an inorganic, colorless, hygroscopic crystalline compound. It has a large mass and is highly soluble in water (1865 g/L). Due to its hygroscopic characteristic, when put in water, it forms a dense solute that is not very viscous. Therefore, it is a good material for ...

Centrifugation to equilibrium in cesium chloride gradients has been used for more than 40 yr to purify viruses. The application of high G-forces for a long period of time to a solution of CsCl generates a density gradient that allows separation of empty, partially packaged, and fully packaged viral particles from cellular debris, proteins, and nucleic …

When a solution of cesium chloride (CsCl) is subjected to high-speed centrifugation, a stable density gradient is formed. Meselson and Stahl found that when cell contents were subjected to centrifugation with a CsCl solution, a band of DNA formed at the CsCl density that matched the density of the DNA. This technique is called density-gradient.

Cesium chloride density gradient ultracentrifugation is the conventional method of purification for adeno-associated viral vectors. This method is often preferred because it allows for good separation of full and empty vector particles, and because it can be adjusted to purify any AAV serotype with minimal optimization. AAV vectors purified by CsCl …

Cesium chloride can also be used as a density medium. Inorganic salts are popular density-gradient media. However, the density of solvated SWCNTs in cesium chloride solutions was found to be approximately 1.4 g cm −3 [36]. Therefore, the concentration of CsCl should be adjusted to be approximately 42.5% (w/w) [36].
