Methods for removal, purification, and concentration of viruses, and methods of therapy based thereupon

   
   

The invention is based on the discovery that certain membranes, which include side chains or molecular "brushes" having, for example, tertiary amino functional groups, can be used as highly effective filters to capture viruses/virus particles from liquids without removal of proteins. New methods based on this discovery include removing viruses from liquids such as blood or plasma, removing viruses from pharmaceuticals, concentrating and/or purifying viruses, e.g., for use in gene therapy, and producing recombinant viruses in new bioreactors. The invention also includes new methods of therapy or adjunct therapy for viral infections, in which a patient's blood or plasma is filtered through the membranes to remove viruses to reduce the viral load. The invention also includes new bioreactors and viral filters containing the membranes.

A invenção é baseada na descoberta que determinadas membranas, que incluem as correntes laterais ou as "escovas molecular" que têm, para o exemplo, amino grupos funcionais tertiary, podem ser usadas como filtros altamente eficazes capturar partículas de viruses/virus dos líquidos sem remoção das proteínas. Os métodos novos baseados nesta descoberta incluem remover os vírus dos líquidos tais como o sangue ou o plasma, remover os vírus dos pharmaceuticals, concentrando e/ou purifying vírus, por exemplo, para o uso na terapia do gene, e em produzir vírus recombinant em bioreactors novos. A invenção inclui também métodos novos da terapia ou da terapia do adjunct para as infecções viral, em que o sangue ou o plasma de um paciente são filtrados através das membranas para remover os vírus para reduzir a carga viral. A invenção inclui também bioreactors novos e os filtros viral que contêm as membranas.
