The invention relates to a porous, non-particulate, polysaccharide matrix having convective permeability onto the surface of which a grafted polymer from at least one ethylene monomer compound having functional groups is attached, the polysaccharide matrix being produced by grafting a porous, non-particulate, polysaccharide starting matrix having convective permeability with the at least one ethylene monomer compound in the presence of an organic acid having at least one carboxylic acid group and/or at least one acidic XH group with X = -O, -S, or –N and a transition metal compound or lanthanoide compound. The polysaccharide matrix according to the invention is characterized by a high protein binding capacity. The invention further relates to methods for producing the polysaccharide matrix and to a use of the polysaccharide matrix for material separation. |
