摘  要:
采用PCR技术从重组克隆载体pGEM-dUTPase中扩增出猪带绦虫六钩蚴dUTPase基因,与表达载体pGFP-C1相连接,构建重组表达质粒pGFP-C1-dUTPase,转化大肠埃希菌DH5α,经测序证实,基因序列完全正确。用脂质体法转染BHK细胞,采用荧光显微镜实时观察和RT-PCR技术确定目的蛋白的表达情况。结果表明,在转染重组质粒48 h后能观察到绿色荧光,表明在BHK细胞中成功地表达了猪带绦虫dUTPase与pGFP-C1的融合蛋白,为下一步重组dUTPase酶活性的研究奠定了基础。

摘  要:
Taenia solium oncosphere dUTPase gene has been amplificated from recombinant cloning vector pGEM-dUTPase by PCR,and expression plasmid pGFP-C1-dUTPase has been constructed by connecting with expression vector pGFP-C1,and then converted Bacillus coli.strain DH5α.Through sequencing,the gene sequence is correct completely.Using Lipofectin to transfect into the BHK cells,by fluorescence microscope to observe fluorescence,expression of the interest protein can be determined.Results:After transfecting 48 hours,the Green fluorescence can be observed under fluorescence microscope The results indicate that fusion protein of dUTPase and pGFP-C1 was successfully expressed in BHK cells.This method can be further used to establish foundation to study enzymatic activity.
