  • Solid phase system for ligand assay
    Patent number: 4786606
    Abstract: A method for conducting a ligand assay in an inert porous medium wherein a binding material is immunologically immobilized within the medium, which includes the steps of immunologically immobilizing a binding material within a finite zone of the medium, applying an analyte to the zone containing the immobilized binding material, applying a labeled indicator to the zone which becomes immobilized within the zone in an amount which can be correlated to the amount of analyte in the zone, applying a solvent to substantially the center of the zone to chromatographically separate the unbound labeled indicator from the zone, and measuring the amount of labeled indicator remaining in the zone.
    Type: Grant
    Filed: March 7, 1985
    Date of Patent: November 22, 1988
    Assignee: Baxter Travenol Laboratories, Inc.
    Inventors: Joseph L. Giegel, Mary M. Brotherton
