摘要: 利用Protean软件对猪戊型肝炎病毒(hepatitis E virus,HEV)swCH189株的ORF2进行潜在抗原位点分析,选取381aa-623aa段作为表达片段,运用PCR方法从ORF2全长质粒中扩增出目的片段cp239,经纯化、连接等,成功构建了表达载体pET32a(+)-cp239,为下一步进行基因原核表达及其生物学活性分析奠定了基础。

Abstract: The test used the Protean software to analyze the potential antigenic sites of ORF2 of HEV swCH189 strain,and selected 381aa to 623aa segment as the expression of target,the cp239 fragment was amplified from the full-length ORF2 plasmid by PCR,after purification,connection,and so on,the prokaryotic expression vector pET32a(+)-cp239 was successfully constructed. This work laid the foundation for the next step of the prokaryotic expression and analysis of biological activity.

Key words: swine; hepatitis E virus; ORF2; construction of prokaryotic expression vector
