| 摘 要： | 采用大肠杆菌表达体系来获得陆地棉锌指蛋白（GZFP）的融合蛋白．以pMD18-GZFP质粒为模板，用PCR方法扩增获得GZFP基因的编码区序列，将其克隆到表达载体pET28b（＋）中，转化宿主菌BL21（DE3），成功地构建了陆地棉GZFP基因原核表达载体pET—GZFP、经IPTG诱导、SDS-PAGE电泳分析和蛋白质杂交检测表明，陆地棉GZFP以融合蛋白的形式在大肠杆菌中得到大量表达．

| Abstract: | In this study,a novel zinc finger protein(GZFP) from upland cotton(Gossypium hirsutum L.)was expressed by the E.coli expression system.The GZFP gene was amplified by PCR with pMD18-GZFP plasmid as the template,and was then cloned into the pET-28b(+) to construct pET-GZFP recombinant plasmid,which was transformed into E.coli BL21(DE3).The recombinant GZFP was induced and expressed by IPTG.SDS-PAGE analysis and Western blotting showed that the target protein was expressed at a high level in E.coli BL21(DE3). |
