differential centrifugation[‚dif·ə′ren·chəl ‚sen·trə·fə′gā·shən] (cell and molecular biology) The separation of mixtures such as cellular particles in a medium at various centrifugal forces to separate particles of different density, size, and shape from each other. differential centrifugation
differential centrifugation a technique in which cell organelles can be separated by centrifuging an homogenate at various speeds, each speed causing sedimentation of a specific cell fraction. The smaller the organelle, the higher the speed required for sedimentation. See DENSITY-GRADIENT CENTRIFUGATION, ULTRACENTRIFUGE, CENTRIFUGATION. |
