The BDDcFⅧ gene was ligated behind PUB and 20H1 promotors to create lentiviral vectors pTK161 and pTK162. Meantime lentiviral vectors pTK161' and pTK162' were produced by cloning a green fluorescent protein into pTK151 and pTK152, which was driven by PUB and 2OH1 promotors respectively. Vector supernatant were prepared by using transfer calcium phosphate mediated-cotransfection of 293T cells. The virus vector,△NRF packaging-plasmid, and VSV-G envelope-plasmid was assayed by titers and cFⅧ activity in cell culture supernatant after infection into 293T cells.

用构建携带cFⅧ基因的慢病毒载体pTK161和pTK162（含20HI启动子），同时构建含绿色荧光蛋白的慢病毒载体pTK161'和pTK162'（含2OH1启动子）的方法，分别与包装质粒△NRF、包膜蛋白质粒VSV-G共转染293T包装细胞，将包装好的病毒颗粒再感染293T细胞，检测病毒滴度和培养细胞上清中cFⅧ活性。
