病毒基因型是丙型肝炎抗病毒治疗方案选择的重要依据,常见的分型方法有测序分析、反向线性杂交、实时荧光PCR等,不同的方法设计各有优势和不足,本文建立了一个荧光PCR结合熔解曲线分析的丙型肝炎病毒(HepatitisCvirus,HCV)分型体系,用以区分中国大陆较常见的HCV1a、1b、2a、3a、3b、6a亚型。实验方法如下:一、制备6个内含HCVRNA核心区核酸序列的病毒样颗粒(HCV假病毒),分别作为6个HCV亚型的替代物/阳性质控品;二、设计通用引物扩增出HCV基因组的核心区,并设计荧光探针与各HCV亚型扩增子杂交,使之得到亚型特异的熔点;三、考察和优化体系的分型能力;四、建立从RNA提...Objective: The genotype of hepatitis C virus (HCV) is a predictor of antiviral therapeutic response, which is to be an important basis for the selection of antiviral therapy. HCV genotypes are usually determined by sequencing, real-time PCR or by the INNO-LiPA test etc. We describe an approach for HCV genotype determination by real-time PCR and melting curve analysis to identify HCV 1a, 1b, 2a, 3...学位:理学硕士院系专业:生命科学学院生物医学科学系_细胞生物学学号:2172006115219
