The PTZ plasmid vector was changed to plasmid vector pSP72, which contains both T7 and Sp6 promotors for transcription of antisense (T7) and sense (Sp6) RNA probe in vitro. The results revealed the label rate of cRNA probe is high, the hybrids between RNA-RNA are stable, so the background of hybridization is satisfactory.

本实验将质粒载体PTZ转换为带有T7和Sp6两个启动基因的pSP72载体，故可在体外转录cRNA时同时得到意义（Sp6为启动基因）和反意义（T7为启动基因）探针，实验结果表明，cRNA探针标记率高，杂合物稳定，故所获杂交反应背景较为满意。

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.
