  • Immunization with bacterial ghost-based vaccines
    Patent number: 7858357
    Abstract: Methods for improving binding of a proteinaceous substance to cell-wall material of a Gram-positive bacterium are disclosed. The proteinaceous substance includes an AcmA cell-wall binding domain, homolog or functional derivative thereof. The method includes treating the cell-wall material with a solution capable of removing a cell-wall component such as a protein, lipoteichoic acid or carbohydrate from the cell-wall material and contacting the proteinaceous substance with the cell-wall material.
    Type: Grant
    Filed: May 1, 2009
    Date of Patent: December 28, 2010
    Assignee: Applied NanoSystems B.V.
    Inventors: Cornelis Johannes Leenhouts, Ranjan Ramasamy, Anton Steen, Jan Kok, Girbe Buist, Oscar Paul Kuipers
