The invention relates to a chromatographic support. The support intended to reduce the adsorption of proteins comprises a porous solid on which is deposited a film of a polymer, consisting of a polyvinylimidazole, a polyvinylimidazole quaternized on nitrogen in position 3 by an alkylating agent, or a copolymer obtained at starting from vinylimidazole and from a copolymerizable hydrophilic monomer, and optionally quaternized. Application to the rapid chromatographic separation of proteins. |
