Patents by Inventor Tracey A. Pownder

Tracey A. Pownder 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).

  • Patent number: 8759066
    Abstract: Disclosed are compositions for activating thrombin precursors to thrombin. The compositions provided include polypeptide compositions wherein the pre-pro-sequence comprises a thrombin cleavage site. The compositions provided also include polynucleotides encoding said polypeptides and recombinant systems for expressing said polypeptides. This disclosure also relates to methods for producing said compositions, recovering said compositions, activating said compositions purifying said compositions and producing active thrombin molecules using the active form of said compositions.
    Type: Grant
    Filed: April 7, 2009
    Date of Patent: June 24, 2014
    Assignee: Zymogenetics, Inc.
    Inventors: Paul D. Bishop, Tracey A. Pownder, Paul O. Sheppard, Christopher J. Stenland

  • Patent number: 7235385
    Abstract: The present invention provides two novel E. coli synthetic promoters, Syn 1 and Syn 2. Syn 1 and Syn 2 are two tight regulated synthetic promoters that control uninduced, leaky expression of proteins that are toxic and interfere with production of recombinant protein from an E. coli expression system.
    Type: Grant
    Filed: February 21, 2006
    Date of Patent: June 26, 2007
    Assignee: ZymoGenetics, Inc.
    Inventors: Chung Chan, Tracey A. Pownder
  • Patent number: 7202077
    Abstract: The increased use of nucleotide sequence data mining techniques has amplified the demand for efficient methods of producing recombinant proteins in prokaryotic cells. A strategy is provided for enhancing the synthesis of recombinant amino acid sequences by improving translation from expression cassettes in vitro before producing recombinant hosts.
    Type: Grant
