Agilent 2100 Bioanalyzer在人乳头瘤病毒检测中的应用

目的：探讨Agilent2100Bioanalyzer芯片分析系统（简称Bioanalyzer)在人乳头瘤病毒（HPV）的PCR检测和分组中的应用。方法：先分别进行通用引物介导PCR（GP－PCR）和型特异性引物介导PCR，扩增HPV高保守区（L1区）的共同序列和各型（包括HPV6，11，16和18型）的特型性序列，然后分别用常规的琼脂糖凝胶电泳技术和Bioanalyzer对PCR产物进行检测，并比较两种检测方法的准确度，重复性和灵敏度。结果：Bioanalyzer在确定片段长度时的准确度和重复性比琼脂糖凝胶电泳高，前者的准确度在95％以上，后者仅为85％，Bioanalyzer的检测灵敏度比琼脂糖凝胶电泳高100倍，结论：Bioanalyzer芯片分析系统结合PCR方法可对HPV进行特异，准确，稳定，灵敏的检测和型别鉴定，具有重要的推广价值。

Application of Agilent 2100 Bioanalyzer in detection of human papilloma virus.

OBJECTIVE: To explore the feasibility of using Agilent 2100 bioanalyzer in the detection and genotyping of human papilloma virus (HPV). METHODS: The consensus sequence of highly conserved region (L1) and genotype-specific gene fragments of all HPV genotypes (including HPV6, 11, 16 and 18) were amplified by PCR technique using general and type-specific primers respectively. Agilent 2100 Bioanalyzer and routine agarose gel electrophoresis were then employed respectively to examine the PCR products, and the accuracy, reproducibility and sensitivity of these 2 detection techniques were compared. RESULTS: Agilent 2100 Bioanalyzer showed better accuracy in determining the length of the gene fragments than agarose gel electrophoresis, the accuracy of the former reaching above 95% while the latter was only 85%. Bioanalyzer was also 100 times more sensitive than agarose electrophoresis. CONCLUSIONS: Agilent 2100 Bioanalyzer combined with PCR is specific, accurate and sensitive for HPV detection and genotyping.
