  • Peptide-based fluorescence polarization assay for detection of antibodies to
    Patent number: 7547506
    Abstract: The present invention provides an assay for detection of M. bovis-infected animals. A tracer, comprising a peptide of M. bovis protein MPB70 conjugated to a fluorophore, is added to a serum sample from an animal to form a mixture. The fluorescence polarization of the mixture in then measured and compared to the fluorescence polarization of a control. The present invention further provides a tracer for use in fluorescence polarization assay to detect antibodies specific for M. bovis. The tracer comprises a peptide of M. bovis protein MPB70 conjugated to a fluorophore, such that the tracer is able to bind to antibodies specific for M. bovis to produce a detectable change in fluorescence polarization.

  • Rapid serological test for paratuberculosis using fluorescence polarization technology
    Patent number: 7018616
    Abstract: The present invention provides an assay for detection of serum antibodies to M. paratuberculosis. A tracer, comprising a carbohydrate antigen isolated from M. paratuberculosis that is conjugated to a fluorophore, is added to a serum sample from an animal to form a mixture. The fluorescence polarization of the mixture is then measured. The presence of serum antibodies to M. paratuberculosis is indicated by a fluorescence polarization value of the mixture that is higher than the fluorescence polarization value of a control. The present invention further provides a tracer for use in a fluorescence polarization assay for antibodies specific for M. paratuberculosis. The tracer comprises a carbohydrate antigen isolated from M. paratuberculosis and conjugated to a fluorophore, such that the tracer is able to bind to antibodies specific for M. paratuberculosis to produce a detectable change in fluorescence polarization.
