A disposable, virus-trapping membrane, and a corresponding method to remove viruses from solution are described. The membrane includes a disposable, micro-porous filter membrane and a ligand immobilized on the membrane. The ligand irreversibly and selectively binds viruses. The ligand also has a pKa sufficiently high to repel antibodies via electrostatic charge repulsion.
La présente invention concerne une membrane jetable destinée à piéger des virus, et un procédé correspondant destiné à retirer des virus d'une solution. La membrane comprend une membrane-filtre micro-poreuse jetable et un ligand immobilisé sur la membrane. Le ligand se lie aux virus de manière irréversible et sélective. Le ligand a aussi un pKa suffisamment élevé pour repousser des anticorps par répulsion des charges électrostatiques.
