The present invention relates to the preparation and use of novel polymeric chromatography media and preferably mixed polymeric chromatography media. According to the invention, the polymeric medium is prepared using polymeric particles derivatized with polyethyleneimine and polyethyleneimine derivatized polymeric particles, preferably further functionalized with appropriate reactants. Polymeric chromatography media are particularly useful for bioseparation.n n n n Polymeric Chromatography Media, Polyethylenimine |
