巨细胞病毒抗原片的制备及其在快速诊断中初步应用

本文报道了用巨细胞病毒(CMV,AD_(169)株)感染的人胚肺细胞(HL)制备CMV抗原片。在这种抗原片上进行的间接免疫酶组化法(IPA)初步应用于CMV的快速诊断,并与补体结合试验(CFT)和免疫荧光技术(IFA)进行了比较。检测103份血清中抗CMV IgG抗体和18例双份血清中抗CMV IgG和IgM抗体的结果表明,本方法是特异的,其结果与CFT和IFA的结果一致。这种方法简便、快速、灵敏,不需要特殊的设备,可广泛用于临床诊断和流行病学调查。     

ToRCH系列酶标诊断试剂的研制

Torch is the abbreviation of four pathgenic microbols Tonoplasma gondic (Toxo), Rubella Virus (RuV), Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV_1-2). A new indirect ELISA reagent to detect the specific IgG and IgM antibody to ToRCH has been prepared. McAbs, labeled with horseradish peroxidase, against human IgG and IgM are used as the second antibodies. Purified Toxo, RuV, CMV, HSV_1-2 are used as antigens to coat wells. The reagent's quality has been tested. The result showed that the reagent has high specificity and low background. The sensitivity is up to 1∶160～640, the precision is high and the coefficient of variation (C.V) is between 1.4%～9.0%. The reagent is stable (stored at 37 ℃ for 4 days, the change range of each target is no more than 15%).
