| 摘 要： | 根据GenBank中注册的AJ272108等序列,参考有关文献,利用引物设计相关软件在HEV ORF2片段的保守区设计并合成1对引物及探针,采用TaqMan探针建立了荧光定量PCR法。以鉴定正确的质粒为模板建立标准曲线,Ct值线性范围为14.89~27.02,相关系数为0.996。本试验建立的猪戊型肝炎病毒ORF2片段基因实时荧光定量PCR方法扩增效率高、线性范围广,为快速检测猪戊型肝炎病毒的绝对定量分析奠定了基础。

| Abstract: | According to registered AJ272108 sequence and other related sequences in GenBank,and referring the liter-atures of Meng and other researchers,a pair of primers and the probe were designed and synthesized for the conser-vative region of HEV ORF2 fragment,and a real-time fluorescence PCR assay was developed by the TaqMan probe.The standard curve was established though using the positive plasmid as template,in which the linear range of Ct value was from 14.89 to 27.02,and correlation coefficient was 0.996.The real-time fluorescence quantitative PCR assay with the efficient amplification and the wide linear range laid a foundation for rapidly detecting the absolute quantitative analysis of swine hepatitis E virus. |
