  • Hapten derivatized capture membrane and diagnostic assays using such membrane
    Patent number: 6291169
    Abstract: The present invention encompasses a capture membrane comprising a porous filter membrane having a hapten bound directly or indirectly to the membrane wherein complexes formed by specific binding having an anti-hapten bound to a binding member of the specifically binding complex are removed from a solution by the hapten as the solution passes through the membrane. In the preferred embodiment biotin is the hapten and avidin or streptavidin is the anti-hapten.
    Type: Grant
    Filed: March 30, 1999
    Date of Patent: September 18, 2001
    Assignee: Molecular Devices Corporation
    Inventors: John D. Olson, Robert F. Zuk, Richard D. Armenta, Charles R. Burke, Viola T. Kung, Edward L. Sheldon
