Patents by Inventor Emerald M. Spencer

Emerald M. Spencer 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).

  • Uses for antibodies which bind to human somatomedin carrier protein subunits
    Patent number: 5624805
    Abstract: This invention relates to polypeptides that are human somatomedin carrier protein subunits and to processes for producing them. The carrier protein subunits bind to human somatomedin-like polypeptides, also known as insulin-like growth factors. The process involves preparation from a human serum fraction, Cohn IV-1, by a molecule of various chromatographic steps.This invention also relates to DNA molecules encoding human somatomedin carrier protein-like polypeptides, recombinant DNA molecules, hosts, processes for producing carrier protein-like polypeptides, human somatomedin carrier protein-like polypeptides produced using those molecules, hosts and processes. The invention relates to DNA molecules and their expression in appropriate hosts. The recombinant DNA molecules contain DNA molecules that code for polypeptides which have a biological activity of the human carrier protein or a human carrier protein subunit capable of binding somatomedins.
    Type: Grant
    Filed: May 12, 1995
    Date of Patent: April 29, 1997
    Assignee: Celtrix Pharmaceuticals, Inc.
    Inventors: Emerald M. Spencer, Carol Talkington-Verser
