Patents by Inventor Eliza N. Fung

Eliza N. Fung 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).

  • Capillaries for use in a multiplexed capillary electrophoresis system
    Patent number: 5695626
    Abstract: The invention provides a side-entry optical excitation geometry for use in a multiplexed capillary electrophoresis system. A charge-injection device is optically coupled to capillaries in the array such that the interior of a capillary is imaged onto only one pixel. In Sanger-type 4-label DNA sequencing reactions, nucleotide identification ("base calling") is improved by using two long-pass filters to split fluorescence emission into two emission channels. A binary poly(ethyleneoxide) matrix is used in the electrophoretic separations.
    Type: Grant
    Filed: June 18, 1996
    Date of Patent: December 9, 1997
    Assignee: Iowa State University Research Foundation
    Inventors: Edward S. Yeung, Huan-Tsang Chang, Eliza N. Fung
