摘要: 本试验首先用RT-PCR方法扩增出H9N2亚型禽流感病的HA基因,大小约1700 bp,将其克隆到真核表达载体pcDNA中,并将该真核表达载体上的CMV启动子控制的含LacZHA基因表达盒克隆人马立克氏病病毒US2基因中,成功的构建了马立克氏病病毒的转移载体。然后,通过脂质体方法转染已感染马立克氏病病毒的鸡胚成纤维细胞(CEF)中,通过蓝斑筛选获得重组病毒。该重组病毒通过PCR方法鉴定证实其基因组中含有完整的HA基因。免疫酶反应和Western-blot证实重组病毒表达了禽流感HA蛋白,表达的HA蛋白具有血凝活性。

关键词: 禽流感病毒, HA基因, 重组马立克氏病病毒

Abstract: In this study, a 1.7 kb DNA fragment encoding the HA gene of Avian influenza virus H9N2 was obtained by RT-PCR and the sequence was cloned into the vector of pcDNA; Then the expression cassette including the HA gene of AIV and LacZ gene of Ecoli controlled by CMV promoter, were inserted into US2 gene of MDV to give a transfer vector. The complex of pUS2 HA and DOTAP was transfected into CEF infected MDV. The recombinant MDV were selected and purified by blue plague. The complete HA gene inserted into MDV was detected by PCR. Western-blot and immunostaining result demonstrated tHAt HA protein of AIV was expressed by recombinant MDV.

Key words: Avian influenza virus, HA gene, Recombinant marek’s disease virus
