A fluorescence polarization assay for Equine Infectious Anemia Virus utilizes a short peptide reagent probe derived from a conserved immunodominant region of gp45. The probe is N-terminally labeled, preferably with 6-carboxyfluorescein, and purified by HPLC, which reacts in a homogenous assay with anti-EIAV antibodies contained in the serum of field infected horses and ponies. The assay has a sensitivity of about 90 percent with a specificity approaching 100 percent.
