Cscl density
WebThe density of DNA can be measured with the help of a technique known as CsCl density gradient centrifugation. A CsCl solution is set up in a centrifuge tube. The CsCl forms a concentration gradient within the tube when centrifuged at high speed, with more concentrated CsCl towards the base. WebSep 22, 2011 · Quantification of CsCl density profiles of HBV virions and naked capsids. The relative levels of HBV DNA, RNA, core protein, and surface proteins associated with the virions or naked capsids in the culture medium of HepG-2 cells transfected with the WT (top), Y63D (middle), or Pol- (bottom) HBV constructs were plotted across the CsCl density.
