  • Multiplexed capillary electrophoresis system
    Patent number: 5741411
    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: April 21, 1998
    Assignee: Iowa State University Research Foundation
    Inventors: Edward S. Yeung, Qingbo Li, Xiandan Lu
