  • Separation matrix for viral purification
    Patent number: 8481298
    Abstract: The present invention relates to a method of preparing a separation matrix comprising at least one insoluble carrier to which sulphate ligands have been attached via extenders, which method comprises coupling, in a first step, of the sulphate ligands to the extenders and, in a subsequent step, attaching the extenders to an insoluble carrier. The invention also relates to a separation matrix comprised of at least one insoluble carrier to which sulphate ligands have been attached via extenders. Advantageously, no sulphate ligands are directly attached to the insoluble carrier. The extenders may be natural polymers, such as dextran, and the insoluble carrier may be made from natural polymers, such as agarose, or synthetic polymers. The invention also relates to a method of purifying virus, such as influenza virus, using a separation matrix according to the invention.
