  • Haptens, tracers, immunogens and antibodies for immunoassays for propoxyphene
    Patent number: 5356820
    Abstract: Disclosed is a substantially optically pure hapten, useful in an immunoassay for dextropropoxyphene and/or nordextropropoxyphene. The hapten corresponds to a specified structural formula (IX).Also disclosed is an immunogen derived from the hapten as well as an antibody raised in response to an immunogen derived from the hapten.Also disclosed is a fluorescent tracer derived from a substantially optically pure compound corresponding to the hapten, the tracer being useful in an immunoassay for dextropropoxyphene and/or nordextropropoxyphene.Also disclosed is an improved immunoassay for determining dextropropoxyphene and/or nordextropropoxyphene in a biological sample involving a step of contacting the sample with antibodies raised in response to the immunogen.
    Type: Grant
    Filed: May 12, 1993
    Date of Patent: October 18, 1994
    Assignee: Abbott Laboratories
    Inventors: Robert E. Dubler, Jonathan Grote, Donna R. Kuhn
