Patent number: 11154821Abstract: A composite liquid filtration platform including a composite filtration medium featuring an electrospun polymeric nanofiber layer collected on a porous membrane. When in use, the porous membrane acts as a prefilter used upstream from the polymeric nanofiber layer to remove particles from a liquid stream flowing through the composite filtration structure. The nanofiber layer, positioned downstream from the porous membrane, is used as the retentive layer for critical filtration to provide biosafety assurance, and is responsible for capturing microorganisms like bacteria, mycoplasma or viruses. The composite liquid filtration platform provided herein exhibits permeability advantages over conventional porous membranes or nanofiber mats spun on coarse non-wovens.Type: GrantFiled: March 30, 2012Date of Patent: October 26, 2021Assignee: EMD Millipore CorporationInventors: Onur Y. Kas, Mikhail Kozlov, Gabriel Tkacik, David Nhiem, Philip Goddard, Sherry A. Leon

Patent number: 10252199Abstract: A method for removing retroviruses from liquid samples and a nanofiber containing liquid filtration medium that simultaneously exhibits high liquid permeability and high microorganism retention is disclosed. Retroviruses are removed from a liquid by passing the liquid through a porous nanofiber containing filtration medium having a retrovirus LRV greater than about 6, and the nanofiber(s) has a diameter from about 10 nm to about 100 nm. The filtration medium can be in the form of a fibrous electrospun polymeric nanofiber liquid filtration medium mat.Type: GrantFiled: March 2, 2017Date of Patent: April 9, 2019Assignee: EMD Millipore CorporationInventors: Onur Y.

Patent number: 8143067Abstract: Hydrophilic membrane particularly suited for blotting applications, preferably Western blotting. A pre-wet hydrophobic membrane substrate, preferably made of PVDF, is contacted with a monomer solution and subjected to a UV-initiated free radical polymerization step to render the substrate permanently hydrophilic. The resulting membrane exhibits low background fluorescence, high protein binding, excellent retention of protein sample spot morphology, and extended dynamic range (high signal-to-noise ratio, enhanced sample detectability). The membrane demonstrates comparable or higher performance in Western blotting applications than conventional nitrocellulose Western blotting membranes, particularly for protein detection at low sample concentrations, and is directly water-wettable, eliminating the need for an alcohol pre-wet step prior to use.Type: GrantFiled: November 3, 2010Date of Patent: March 27, 2012Assignee: EMD Millipore CorporationInventors: Antoni Peters, Philip Goddard, John Charkoudian, Neil Soice, Dave Brewster, Anja Dedeo
