Patents by Inventor James L. Van Etten

James L. Van Etten 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).

  • Promoters from chlorella virus genes providing for expression of genes in prokaryotic and eukaryotic hosts
    Patent number: 6673537
    Abstract: The invention is directed to novel promoters or mutants thereof from Chlorella virus DNA methyltansferase genes. A Chlorella virus gene promoter is operably linked to a first and/or second DNA sequence encoding a gene that is different from the Chlorella virus to form an expression cassette. An expression cassette can be introduced into prokaryotic and/or eukaryotic cells and can provide for a high level of expression of the gene encoded by the first and/or second DNA sequence. The invention also provides a method for screening other Chlorella virus genes for promoters that can function to express a heterologous gene in prokaryotic and/or eukaryotic hosts.
    Type: Grant
    Filed: October 12, 1999
    Date of Patent: January 6, 2004
    Assignee: Board of Regents, University of Nebraska-Lincoln
    Inventors: Amitava Mitra, James L. Van Etten
