    Buoyant density centrifugation Wikipedia

    Implementation. Historically a caesium chloride (CsCl) solution was often used, but more commonly used density gradients are sucrose or Percoll.The sample is put on top of the solution, and then the tube is spun at a very high speed for an extended time, at times lasting days.

    Density Gradient Ultracentrifugation Protocol

    In this case, the gradient cannot be made of sucrose, because sucrose is less dense than nucleic acids. Instead, cesium chloride gradients, typically from 1.65 to 1.75 g/mL are used, as they have sufficient density and a low viscosity. Here we see plankton DNA being purified using a continuous cesium chloride gradient.

    Caesium Chloride an overview ScienceDirect Topics

    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].

    What makes some chemicals form steep density gradients

    11-04-2020· Caesium chloride and sucrose are both suitable for isopycnic centrifugation, and presumably not much else is. I'm unclear as to the mechanism by which they form useful density gradients. Wikipedia says, The $\ce{CsCl}$ molecules become densely packed toward the bottom, so even layers of different densities form. (No doubt $\ce{CsCl}$ is molecular, despite being the chloride

    Isopycnic Wikipedia

    Isopycnic centrifugation refers to a method wherein a density gradient is either pre-formed or forms during high speed centrifugation. After this gradient is formed particles move within the gradient to the position having a density matching their own (this is in fact an incorrect description of the exact physical process but does describe the result in a meaningful way).
