AbstractDisclosed 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. Also disclosed is a fluorescence polarization immunoassay (FPIA) for determining dextropropoxyphene and/or nordextropropoxyphene involving a step of contacting the sample with antibodies raised in response to the immunogen, and/or involving a step of contacting the sample with a fluorescent tracer.Other References
