To construct the recombinant fowlpox virus expression plasmid pUTA-GAG-IL6, IL-6 and HIV-1 gag gene were inserted into the downstream of P7.5 tandem promoter and combined promoter ATI-P7.5 of fowlpox virus expression vector pUTAL respectively.

• 分别将IL-6和HIV-1 gag基因插入到鸡痘病毒表达载体质粒pUTAL串联启动子和复合启动子(ATI-P7.；5)下游；构建了重组鸡痘病毒表达质粒pUTA-GAG-IL6。
