Positively Charged Membrane

View page
US Patent:
6780327, Aug 24, 2004
Filed:
Dec 12, 2001
Appl. No.:
09/914163
Inventors:
Xiaosong Wu - Pensacola FL
Chung-Jen Hou - Pensacola FL
Jayesh Dharia - Pensacola FL
Peter Konstantin - Heinade,
Yujing Yang - Pensacola FL
Assignee:
Pall Corporation - East Hills NY
International Classification:
B01D 6114
US Classification:
210660, 210488, 210490, 21050021, 21050037, 21050038, 2105021, 427245, 521 27
Abstract:
The present invention provides a positively charged microporous membrane having a protein binding capacity about 25 mg/ml or greater comprising a hydrophilic porous substrate and a crosslinked coating that provides a fixed positive charge to the membrane. The present invention further provides a positively charged microporous membrane comprising a porous substrate and a crosslinked coating comprising pendant cationic groups. The membranes of the present invention find use in a variety of applications including ion-exchange chromatography, macromolecular transfer, as well as detection, filtration and purification of biomolecules such as proteins, nucleic acids, endotoxins, and the like.

US Patent:
6783937, Aug 31, 2004
Filed:
Dec 12, 2001
Appl. No.:
09/914165
Inventors:
Chung-Jen Hou - Pensacola FL
Peter Konstantin - Heinade,
Yujing Yang - Pensacola FL
Assignee:
Pall Corporation - East Hills NY
International Classification:
C12Q 168
US Classification:
435 6, 210483, 210490, 21050035, 21050038, 21050041, 264 41, 427244, 435 4, 435180, 436 86, 436 94
Abstract:
The present invention provides, in certain embodiments, a negatively charged microporous membrane comprising a porous substrate and a crosslinked coating having fixed negative charges. The crosslinked coating can be prepared, e. g. , from a polymerized composition comprising an unsaturated monomer having an anionic group, an N-(hydroxymethyl)- and/or N-(alkoxymethyl)-acrylamide, a hydrophilic unsaturated monomer, and an initiator. The present invention further provides, in some embodiments, a negatively charged microporous membrane comprising a porous substrate and a crosslinked coating prepared from a polymerized composition comprising an unsaturated monomer having an anionic group, an N-(hydroxymethyl)- or N-(alkoxymethyl)-acrylamide, a polysaccharide, and an initiator. The membranes of the present invention are suitable for use in ion exchange chromatography, for example, in the separation and purification of positively charged species such as proteins.

International Classification:
B01D 6912
US Classification:
210660, 210488, 210490, 21050024, 21050027, 21050041, 2105021, 210504, 264 41, 427244, 427245, 427487, 436178, 521 27
Abstract:
The present invention provides a hydrophilic charged microporous membrane comprising a porous hydrophobic substrate and a coating comprising a charge-providing agent. The present invention further provides a hydrophilic charged membrane comprising a porous hydrophobic substrate and a hydrophilic charge-providing agent distributed within the substrate. The present invention further provides a filter as well as a filter device comprising the inventive hydrophilic charged membrane. The present invention further provides a process for treating a fluid containing bacterial contaminants such as endotoxins comprising contacting the membrane with the fluid to provide a bacterial contaminant depleted fluid.
