density gradient centrifugation

a procedure for separating particles such as viruses or ribosomes or molecules such as DNA in which the sample is placed on a preformed gradient such as sucrose or cesium chloride. Upon centrifugation either by rate zonal or equilibrium procedures, the macromolecules are 'banded' in the gradient and can be collected as a pure fraction.
