SEPARATION MEDIUM AND METHOD FOR ITS PREPARATION

摘要

The present invention relates to a method of preparing a separation medium, which method comprises to provide a slurry of essentially spherical polymer beads in an aqueous solution of a natural polymer and contacting the slurry with an organic solvent in the presence of emulsifier to allow aggregation o f the beads. In a preferred embodiment, the natural polymer is agarose. The present invention also encompasses a separation medium comprised of one or more aggregates, wherein each aggregate comprises a plurality of porous and essentially spherical polymer beads assembled by a porous gel.
