Cytomegalovirus antibodies were measured in human sera by a nuclear anticomplement immunofluorescence test that used as antigen the isolated nucleic of virus-infected fibroblasts 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 either indirect hemagglutination (P < 0.02) or complement fixation with a glycine-extract antigen (P < 0.001).
采用核抗补体免疫荧光试验检测人血清中的巨细胞病毒抗体,该试验以在蒸馏水中裂解的病毒感染成纤维细胞的分离核酸作为抗原。与应用于相同分离核底物的传统全细胞抗补体免疫荧光试验或间接荧光抗体试验相比,该方法显示出较少的非特异性荧光。该检测法在40份抗体阳性血清中检测出97.5%,而间接血凝试验和补体结合试验的检测率分别为92.5%和90%。此外,通过该技术获得的抗体滴度显著高于通过间接血凝试验(P < 0.02)或用甘氨酸提取物抗原进行补体结合试验获得的抗体滴度(P < 0.001)。
