IMMUNOENZYMOMETRIC TEST SYSTEM FOR SEROLOGIC DIAGNOSIS OF REOVIRUS INFECTION IN CATTLE AND MONITORING OF POST-VACCINATION IMMUNITY LEVEL Russian patent published in 2013 - IPC G01N33/53 G01N33/569 G01N33/543 A61K39/15 

FIELD: veterinary medicine.

SUBSTANCE: invention relates to immunoenzymometric test system for serologic diagnosis of reovirus infection in cattle and the monitoring of post-vaccination immunity level. The presented immunoenzymometric test system comprises a specific antigen of the strain "Reo 1 Lang-DEP" of reovirus of type I, inactivated by 0.08% solution of 1,2-aminoethylaziridine representing a specific protein in a concentration of 5-10 mkg/cm³ adsorbed on the surface of polystyrene cavities in carbonate-bicarbonate buffer with merthiolate in a final concentration of 0.1-0.2 mg/cm³, a control positive serum obtained to the antigen of reovirus of type I with the activity in IFA 1:3200-1:6400, control negative serum, anti-species conjugate, potassium dihydrogen phosphate, potassium phosphate dibasic, sodium chloride, a chromogen (ortho-phenylenediamine), hydrogen peroxide, stop reagent and panels for carrying out reaction of the immunoenzymatic assay.

EFFECT: test system enables to diagnose reovirus infection of cattle with high sensitivity.
