Fig. 2From: Monoclonal antibodies specific for the hemagglutinin-neuraminidase protein define neutralizing epitopes specific for Newcastle disease virus genotype 2.VII from EgyptAntibody response of immunized mice and reactivity of obtained MAb. Antibody response of two mice immunized with the S3 antigen preparation were tested at indicated times after the first immunization by HI (filled symbols) and by ConA ELISA (white symbols) (a). Time of booster immunizations are given as triangles (filled triangle). In addition, ConA ELISA reactivity of HI positive MAbs (b) or HI-negative cloned MAbs (c) is givenBack to article page
