  • Modified toxin
    Patent number: 7144576
    Abstract: The development of subunits and subunit analogs of the Bordetella exotoxin by recombinant DNA techniques provides vaccine products that retain their biological activity, are highly immunogenic, and can confer protection against disease challenge. Genetically-engineered modifications of the subunits can result in products that retain immunogenicity, yet are free of enzymatic activity associated with toxin of reactogenicity.
    Type: Grant
    Filed: May 24, 1995
    Date of Patent: December 5, 2006
    Assignee: Amgen, Inc.
