    摘要: The present invention is directed to affinity chromatography devices that separate a targeted protein or antibody from an aqueous mixture containing the targeted protein or antibody. The chromatography device may contain a stacked membrane assembly or a wound membrane assembly. The membrane assemblies include (1) at least one polymer membrane that contains therein inorganic particles and (2) at least one impermeable layer (e.g., a thermoplastic polymer in a solid state). The polymer membrane and/or the inorganic particles have an affinity ligand bonded thereto. The affinity ligand may be a protein, an antibody, or a polysaccharide that reversibly binds to the targeted protein or antibody. The chromatography device may be repeatedly used and may be cleaned with a caustic solution between uses. The chromatography devices has a dynamic binding capacity (DBC) of at least 30 mg/ml (or 0.07 micromol/ml) at 10% breakthrough at a residence time of 20 seconds or less.

    摘要: The present invention is directed to an affinity chromatography device that has a normal flow and which separates a targeted protein from aqueous mixtures. The chromatography device includes a housing containing therein a spiral wound membrane assembly that includes at least one inner intermediate material that forms an outer flow channel, at least one polymer membrane that contains therein inorganic particles, and at least one outer intermediate material that forms an inner flow channel sequentially positioned around a central core having a solid outer wall. An aqueous mixture is passed through the outer flow channel, through the polymer membrane where the targeted protein is removed, and then through an inner flow channel. The affinity chromatography device further includes an inlet flow distributor containing an inlet and an outlet flow distributer containing an outlet. Additionally, the chromatography device has a dimensionless resistance parameter that is less than 0.08.
