    • Solubilized antigens of C. trachomatis strain LGV-434 upon analysis using two-dimensional immunoelectrophoresis yielded a single antigen which was found to be consistently precipitated by sera of patients with C. trachomatis infections. This antigen as antigen-antibody complex was employed as an immunogen to prepare a rabbit monospecific antiserum to this component or antigen. This monospecific antiserum demonstrated the presence of the antigen in each of the 15 strains of C. trachomatis organisms and was non-reactive with strains of C. psittaci. The C. trachomatis specific antigen was purified by immunoadsorption chromatography using monospecific antiserum as a specific ligand covalently bound to agarose gel columns and the resulting purified antigen employed to detect antibody from the sera of lymphogranuloma venereum patients using counterimmunoelectrophoresis. When the C. trachomatis specific antigen is isotopically labeled and utilized in the highly sensitive radioimmune assay antibody to the antigen should be demonstrated and a serological test based thereon should be applicable for the serological diagnosis of non-gonococcal urethritis (NGU).
    • 使用二维免疫电泳分析后,沙眼衣原体菌株LGV-434的溶解性抗原产生单一抗原,其被发现由沙眼衣原体感染患者的血清一致地沉淀。 将该抗原作为抗原 - 抗体复合物用作免疫原,以制备该成分或抗原的兔单特异性抗血清。 这种单特异性抗血清证实了15种沙眼衣原体生物体中的每一种中存在抗原,并且与鹦鹉热鹦鹉with菌株无反应。 沙眼衣原体特异性抗原通过免疫吸附色谱纯化,使用单特异性抗血清作为与琼脂糖凝胶柱共价结合的特异性配体,所得到的纯化抗原用于使用抗免疫电泳从淋巴肉芽肿患者的血清检测抗体。 当沙眼衣原体特异性抗原被同位素标记并用于高度敏感的放射免疫测定中时,应该证明抗原抗体的抗体,并且其基础上的血清学检测应适用于非淋球菌性尿道炎(NGU)的血清学诊断。
