  • Patent number: 6569426
    Abstract: Viruses are modified by coupling a polymer such as polyethylene glycol to obtain polymer-modified viruses that can exhibit reduced antigenicity while retaining infectivity, and which may exhibit increased circulation time in vivo. The polymer may be directly covalently attached or indirectly covalently attached via an intermediate coupling moiety to the virus. The polymer may also be indirectly noncovalently attached to the virus via a ligand such as an antibody having specificity for a viral surface component. To prepare the polymer-modified virus, the polymer is activated and coupled to the virus. A preferred activated polymer is tresyl-monomethoxypolyethylene glycol having an average molecular weight of about 5000 daltons. The polymer-modified viruses have utility for therapeutic and diagnostic in vivo applications, and may be used to introduce a transgene into a target cell by infection, or be administered to a subject having a tumor where the polymer-modified virus localizes to the tumor.

  • Patent number: 6287857
    Abstract: This invention describes a nucleic acid delivery vehicle construct for transfecting and/or infecting a target cell. The construct is made of a delivery vehicle and a bifunctional complex for linking the delivery vehicle to a target cell. The bifunctional complex has a delivery vehicle-binding molecule or fragment (“delivery vehicle-binding portion”), a molecule or fragment thereof that binds to a cell surface molecule on the target cell (“cell surface molecule-binding portion”) and a linker which connects the molecules or fragments.

  • Patent number: 5939536
    Abstract: The present invention provides a method for purifying a membrane associated protein, e.g., cystic fibrosis transmembrane conductance regulator (hereinafter CFTR) in a functional form. The method involves contacting a membrane-associated protein-membrane fraction complex with a detergent forming a solubilized complex and chromatographically isolating the membrane-associated protein from the solubilized complex in a functional form. The functional form of the purified membrane-associated protein of the present invention preferably is sufficiently pure to allow its introduction into humans for therapeutic purposes.
