Keith G. McCullagh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Covalently linked polypeptide cell modulators such as interferon-lymphotoxin conjugates
    Patent number: 5114711
    Abstract: Described is a new class of polypeptide cell modulators characterized by being composed of two covalently linked cell modulators in a linear polypeptide sequence. Such dual function polypeptides have new and particularly useful activities when the component polypeptide cell modulators are interferons, lymphokines or cytotoxins which act through different and specific cell receptors to initiate complementary biological activities.
    Type: Grant
    Filed: July 13, 1989
    Date of Patent: May 19, 1992
    Assignee: G. D. Searle & Co.
    Inventors: Leslie D. Bell, Keith G. McCullagh, Alan G. Porter
