centrifugation
centrifugation (sen·trifˈ·y
·gāˑ·shn),n the process by which substances are separated by cen-trifugal force to increase the rate of filtration or sedimentation of two immiscible liquids or a liquid and a solid.
centrifugation
the process of separating lighter portions of a solution, mixture or suspension from the heavier portions by centrifugal force.
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.
centrifugation
Lab technology The process of separating fractions of systems in a centrifuge. See Axial centrifugation, Density gradient centrifugation, Ultracentrifugation.
