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.

Density Gradient Media and Centrifugation Overview

Density gradient centrifugation is commonly used for the isolation of specific cell populations from whole blood. This technique takes advantage of the differences in density between the various leukocytes and the density gradient medium. As a result, the particular cell populations isolated will depend on the density of the medium that is used.
