  • Publication number: 20080131912
    Abstract: Recombinant antibodies, including chimeric antibodies, specific for hepatitis C (HCV) antigenic proteins are provided. The recombinant antibodies specifically bind to diagnostically relevant regions of HCV proteins and are thus suitable for use, for example, as diagnostic reagents for the detection of HCV, and/or as standardization reagents or positive control reagents in assays for the detection of HCV. The recombinant antibodies can also be used in the treatment or prevention of a HCV infection.

  • Patent number: 5407834
    Abstract: The present invention is directed to a fluorescence polarization assay for phencyclidine and phencyclidine derivatives, to the various components needed for preparing and carrying out such an assay, and to methods of making these components. Specifically, tracers, immunogens and antibodies are disclosed, as well as methods for making them, and a reagent kit containing them. The tracers and the immunogens are made from substituted phencyclidine compounds. A fluorescein moiety is included in the tracer, while a poly(amino acid) forms a part of the immunogen. The assay is conducted by measuring the degree of polarization retention of plane polarized light that has been passed through a sample containing antiserum and tracer.
