作者评价了编码流感病毒ＴｙＩｒ８３和ＨＫ９７株血凝素（ＨＡ）的ＤＮＡ疫苗在小鼠中的同源和异源保护作用。用巨细胞病毒立即早期启动子和鸡β肌动蛋白启动子将ＨＡ基因的全长ＣＤＮＡ拷贝分别克隆到表达载体ｐＪＷ４３０３和ｐＣＡＧＧＳ／ＭＣＳ获得ｐＴｙＩｒＨＡ和ＰＨ?
The authors evaluated the homologous and heterologous protection of DNA vaccines encoding hemagglutinin (HA) of influenza viruses TyIr83 and HK97 in mice. The full-length CDNA copies of the HA gene were cloned into the expression vectors pJW4303 and pCAGGS / MCS, respectively, using the cytomegalovirus immediate early promoter and chicken β-actin promoter to obtain pTyIrHA and PH?
