Mineral carrier used in the chromatographic separation of proteins, and preparation process.

摘要

The support intended to reduce the adsorption of proteins comprises a porous solid onto which is deposited a film of a polymer consisting of a polyvinylimidazole, a polyvinylimidazole quaternised with an alkylating agent on the nitrogen in position 3 or a copolymer obtained from vinylimidazole and from a copolymerisable hydrophilic monomer and optionally quaternised. Application to fast chromatographic separation of proteins.
