PHASE SUPPORTS FOR THE PARTITION CHROMATOGRAPHY OF MACROMOLECULES, A PROCESS FOR THEIR PREPARATION AND THEIR USE

摘要

Phase supports for the partition chromatography of macromolecules, composed of non-adsorptive base support particles which are insoluble in the phase system and have an average particle size within the range from 7 to 2000 .mu.m, the surface of which is coated with a material which is insoluble in the phase system, adheres firmly and has an affinity for one of the phases of the phase system for the partition chromatography, a process for their preparation and their use for separating, by partition chromatography, macromolecules, biopolymers, subcellular units and whole cells, in particular in an aqueous polyethylene glycol/dextran two-phase system.
