METHOD FOR SEPARATING COMPONENTS IN A MIXTURE

摘要

26950 A method is disclosed for separating a material of interest from a mixture containing the material of interest and other insoluble or soluble components. The method comprises binding the material of interest to a bead (MI-bead) in a liquid medium. The MI-bead has a density greater than the aqueous medium. The density of the aqueous medium, or of a second liquid medium in contact with the aqueous medium, is greater than that of the insoluble components in the medium. Next, the medium is subjected to a centrifugal force sufficient to separate the MI-bead from the other components. In one embodiment, the aqueous medium is layered with a medium of at least equal density as, and higher viscosity than, the aqueous medium prior to subjecting to a centrifugal force.
