  • Method of performing immunochromatography
    Patent number: 6210898
    Abstract: The invention relates to multiplex ligase chain reaction (LCR). Two or more putative target sequences are selected. For each one, a set of four probes is used simultaneously to amplify the putative sequence if it is present in the sample. Preferably, all the amplicons are labeled with a common label/hapten and, for each different target, with a unique label/hapten. The invention also relates to an immunochromatographic strip device and method employing a diagonal array of capture spots.
    Type: Grant
    Filed: September 16, 1999
    Date of Patent: April 3, 2001
    Assignee: Abbott Laboratories
    Inventors: Stanley R. Bouma, Julian Gordon, Joanell Hoijer, Cynthia Jou, James Rhoads

  • Method of multiplex ligase chain reaction
    Patent number: 5869252
    Abstract: The invention relates to multiplex ligase chain reaction (LCR). Two or more purative target sequences are selected. For each one, a set of four probes is used simultaneously to amplify the putative sequence if it is present in the sample. Preferably, all the amplicons are labeled with a common label/hapten and, for each different target, with a unique label/hapten. The invention also relates to an immunochromatographic strip device and method employing a diagonal array of capture spots.
