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.[著者文摘]

Abstract:
In this study, a novel zinc finger protein (GZFP) from upland cotton (Gossypiurn 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).[著者文摘]
