Monoclonal antibody based dot-enzyme linked immunosorbent assay (Dot-ELISA) and agar gel precipitation test (AGPT) for identification of Newcastle disease virus (NDV)

Two mouse monoclonal antibodies (MAbs), viz. 2B7 and 2 D10 raised against haemagglutinin-neuraminidase glycoprotein of Newcastle disease virus (NDV) were used to identify several other field isolates and vaccine strains of NDV. These MAbs reacted specifically with all the NDV strains/isolates in Dot-ELISA whereas, only MAb 2D10 reacted with all the NDV strains/isolates in agar gel precipitation test. These two tests employing the MAbs were standardised for rapid diagnosis and identification of NDV.
