Monoclonal blocking ELISA detecting serum antibodies to the glycoprotein gII of Aujeszky's disease virus.
A monoclonal blocking enzyme-linked immunosorbent assay (ELISA) for detection of antibodies to Aujeszky's disease virus (ADV) in porcine serum was developed. This ELISA is based on the reaction between virus antigen immobilized in a microdilution plate and a monoclonal antibody (MAb) reactive with a highly stable epitope on a glycoprotein complex, gII, of ADV. The viral epitope was expressed by 18 European field, laboratory and vaccine strains of ADV. The MAb used in the test was selected among 15 MAbs all reactive with viral epitopes apparently recognized by the porcine immune system as well. Good agreement was found when serum samples from 375 pigs were tested in both a polyclonal and the monoclonal blocking ELISA.
