Then pLHCX/TH and pLNCX_2/AADC were transfected into packaging cell line PA317 with liposome. PA317/TH andPA317/AADC were selected by different antibiotics. Gene expression was examined by methods of immuno-histochemistry and in situ hybridization.

• 我们分别构建了重组逆转录病毒载体pLHCX/TH及pLNCX_2/AADC,通过脂质体介导将带有目的基因的载体分别转到包装细胞PA317中,经筛选得到产病毒的细胞PA317/TH和PA317/AADC,采用免疫组化、原位杂交方法检测目的基因表达;
