title: Antibody-dependent enhancement of plaque formation on cell lines of macrophage origin - a sensitive assay for antiviral antibody.
abstract: An assay for antiviral antibody based on antibody-dependent plaque enhancement (ADPE) in the macrophage cell line P388D1 is described which is as sensitive as, or more sensitive than a radioimmune assay. The method is applicable to a range of Togaviridae and Bunyaviridae although not to Picornaviridae and Herpesviridae. The variables affecting the assay are investigated.
