Figure 1

Diagram of particle behaviour during differential centrifugation and density gradient centrifugation. a) During the differential centrifugation of a suspension of particles in a centrifugal field, the movement of the particles depends on their density, shape and size. b) To separate the biological particles by means of a density gradient, the samples are layered on the prepared gradient before centrifugation. To achieve separation, the sample is centrifuged, until the isopycnic position for the desired particles in the gradient is achieved.
