摘    要:根据反义RNA作用原理,以禽流感病毒(AIV)H14N5 cDNA全长及5’端235个bp为目的基因,反向插入反转录病毒载体 pLXSN中,命名为 pLXSN-NP及 pLXSN-NP,用脂质体包裹重组质粒转染包装细胞 PA317,G418筛选抗性克性,扩增单个克隆后提取包装细胞上清的病毒RNA(vRNA),以巢式PCR方法检测,以及用包装细胞上清(重组病毒)感染滴定细胞系NIH3T3,表明已筛选出产毒的的克隆细胞质,得到重组逆转录病毒,为反义RNA抑制禽流感病毒复制的实验研究奠定了物质基础。

关 键 词:反义RNA  禽流感病毒  逆转录病毒载体  巢式PCR

Abstract:According to the theory of antisense RNA,we inserted full-long the cDNA of NP gene and 5' and 235bp of AIV H14N5 into retroviral vector pLXSN, named pLXas-NP and pLXas-5 '-NP respectively. The retroviral plasmid were transfected into packaging cell line PA317 with lipofectin, then by G418 colony screening method. Firstly the virus RNAs(vRNA)were extracted from the virus-containing super- natant of packaging cell lines, detected the vRNA by Nested-PCR. Secondly infect NIH3T3 with the virus-containing supernatant. Screened the high-titer clones.The recombinant retroviruses were obtained.The way is a rapidly and simply preparation for latter research.
Keywords:Antisense RNA  Avian influenza virus  Retrovirus  Retrovirus vector  Nested PCRl
