Abstract
Cytomegalovirus antibodies were measured in human sera by a nuclear anticomplement immunofluorescence test that used as antigen the isolated nuclei of virus-infected fibroblast cells lysed in distilled water. The method exhibited less nonspecific fluorescence than either a conventional whole-cell anticomplement immunofluorescence test or an indirect fluorescent antibody test applied to the same isolated nuclear substrate. The assay detected 97.5% of 40 antibody-positive sera, compared with 92.5 and 90% detection rates by indirect hemagglutination and complement fixation, respectively. In addition, antibody titers obtained by this technique were significantly higher than those obtained by indirect hemagglutination (P < 0.02) or complement fixation with a glycine-extract antigen (P < 0.001).This publication has 17 references indexed in Scilit:
