5′端帽状结构对多数病毒RNA的稳定性和感染性具有重要作用,而对另一些病毒的RNA则非必需〔1~3〕。乙脑病毒基因组为单股正链RNA,长约11kb,5′端有帽状结构,3′端无PolyA〔4,5〕。为了验证5′mGpppA对乙脑病毒RNA稳定性和感染性的作
The 5 ’cap has an important role in the stability and infectivity of most viral RNAs, but not in other viral RNAs [1-3]. JE virus genome is a single positive strand RNA, about 11kb, 5 ’end cap-like structure, 3’ PolyA [4,5]. To verify the stability and infectivity of 5 ’mGpppA to JEV RNA
