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.Type: GrantFiled: October 31, 2002Date of Patent: March 28, 2006Assignees: Diachemix LLC, Her Majesty the Queen in Right of Canada as represented by the Canadian Food Inspection AgencyInventors: Om P.
