WebDensity gradient centrifugation, developed by Brakke (1951, 1960), is a method that can be used for both isolation and assay of plant viruses. It has proved to be a highly versatile technique and has been widely used in the fields of virology and molecular biology. WebCentrifugation is a mechanical process that utilizes an applied centrifugal force field to separate the components of a mixture according to density and/or particle size. The principles that govern particle behaviour during centrifugation are intuitively comprehensible.
