  • Method for overexpression of zwitterionic polysaccharides
    Publication number: 20080057565
    Abstract: The present invention is directed to methods for producing and selecting novel mutant strains of B. fragilis that constitutively express a particular capsular polysaccharide or only selected capsular polysaccharides; compositions directed to the novel mutant strains of B. fragilis that constitutively express a particular capsular polysaccharide or only selected capsular polysaccharides; improved methods for purification of individual capsular polysaccharides; and compositions directed to novel res02 and inv19 genes and their gene products. Significantly, the present invention provides methods and compositions for overexpressing and purifying immunomodulatory capsular polysaccharide A (PSA) in high yield.
    Type: Application
    Filed: August 20, 2007
    Publication date: March 6, 2008
    Applicant: The Brigham and Women's Hospital, Inc.
    Inventors: Laurie Comstock, Michael Coyne, Dennis Kasper, Arthur Tzianabos, Katja Weinacht
