density-gradient centrifugation isopycnic centrifugation https://orcid.org/0000-0001-5985-7429 equilibrium centrifugation CHMO:0002507 2009-06-19T02:20:10Z sedimentation equilibrium centrifugation A method where the components of a sample are separated on the basis of their density, in a density gradient of e.g. CsCl in a centrifuge, according to buoyant density. The species in the sample move through the gradient until they reach a point where their density and that of the gradient are identical. CHMO:0002018
