Publication number: 20240042348Abstract: Affinity chromatography devices that include a fibrillated heat treated polymer membrane that contains inorganic particles having a spherical shape and a particle size distribution that has a D90/D10 less than or equal to 3 are disclosed. A blend or combination of spherical inorganic particles having a nominal particle size from about 5 microns to about 20 microns may be utilized. Also, the devices have a hydraulic permeability from about 200(×10?12 cm2) to about 700(×10?12 cm2). The affinity chromatography devices have a dynamic binding capacity (DBC) greater than 35 mg/ml at 10% breakthrough at a residence time of 20 seconds. Additionally, the affinity chromatography devices have a cycling durability of at least 100 cycles without exceeding an operating pressure of 0.3 MPa. Manifolds containing multiple affinity chromatography devices and manifolds in a parallel configuration are also disclosed.Type: ApplicationFiled: September 10, 2021Publication date: February 8, 2024Inventors: Jared M. CLINGER, EuiJun KIM, Kevin J. MABE, Michael C. MCMANAWAY, Eric VAN VOORHEES

Publication number: 20230356109Abstract: The present disclosure is directed to affinity chromatography devices including a fibrillated polymer membrane that contains inorganic particles having a spherical shape and a particle size distribution that has a D90/D10 less than or equal to 3. A blend or a combination of spherical inorganic particles may be utilized. A nominal particle size of the spherical inorganic particles is from about 5 microns to about 20 microns. An affinity ligand may be bonded to the spherical inorganic particles and/or to the fibrillated polymer membrane. Also, the affinity chromatography devices have a hydraulic permeability from about 100 (×10?12 cm2) to about 500 (×10?12 cm2). Additionally, the affinity chromatography devices have a cycling durability of at least 100 cycles without exceeding an pressure of 0.3 MPa. Manifolds containing multiple affinity chromatography devices in a parallel configuration and multiple manifolds in a parallel configuration are also disclosed.Type: ApplicationFiled: September 28, 2021Publication date: November 9, 2023Inventors: Jared M.

Publication number: 20220032209Abstract: 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.Type: ApplicationFiled: November 5, 2018Publication date: February 3, 2022Applicant: W. L.

Patent number: 10974170Abstract: 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 at least one polymer membrane that contains therein inorganic particles. 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 may have 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.Type: GrantFiled: November 20, 2019Date of Patent: April 13, 2021Assignee: W.
