Abstract

An overnight assay, based on staining cytomegalovirus-infected cells with monoclonal antibody to the 72,000-molecular-weight major immediate-early viral protein, was compared with a conventional 14-day plaque assay for quantitation of cell-free stocks of cytomegalovirus laboratory strain AD-169 and 20 other clinical strains. Viral titers were quantitatively similar when determined by either method, but centrifugation of monolayers during inoculation enhanced viral infectivity an average of 4.1-fold. When used for scoring neutralizing antibody assays, monoclonal antibody staining yielded titers within one dilution of 14-day plaque-reduction assays in 54 of 56 titrations. Of 21 cytomegalovirus strains, 2 were not recognized by the monoclonal antibody used. Assay with monoclonal antibody offers a rapid and accurate alternative to plaque assays for quantitation or neutralization of cytomegalovirus.

摘要

基于用针对分子量为72,000的主要立即早期病毒蛋白的单克隆抗体对巨细胞病毒感染细胞进行染色的过夜检测法,与用于定量巨细胞病毒实验室毒株AD - 169和其他20种临床毒株的无细胞毒株的传统14天蚀斑检测法进行了比较。通过任一种方法测定时,病毒滴度在数量上相似,但接种期间单层细胞的离心平均使病毒感染性提高了4.1倍。当用于中和抗体检测的评分时,在56次滴定中的54次中,单克隆抗体染色产生的滴度与14天蚀斑减少检测法的滴度相差不超过一个稀释度。在21种巨细胞病毒毒株中,有2种未被所用的单克隆抗体识别。用单克隆抗体进行检测为巨细胞病毒的定量或中和提供了一种快速且准确的替代蚀斑检测法的方法。
