Amy Kuang-Hsu 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).

  • Promoter and plasmid system for genetic engineering
    Patent number: 8168608
    Abstract: This invention provides a series of low-copy number plasmids comprising restriction endonuclease recognition sites useful for cloning at least three different genes or operons, each flanked by a terminator sequence, the plasmids containing variants of glucose isomerase promoters for varying levels of protein expression. The materials and methods are useful for genetic engineering in microorganisms, especially where multiple genetic insertions are sought.
    Type: Grant
    Filed: November 5, 2010
    Date of Patent: May 1, 2012
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Mark S. Payne, Stephen K. Picataggio, Amy Kuang-Hsu, Ramesh Velayudhan Nair, Fernando Valle, Philippe Soucaille, Donald Eugene Trimbur
