摘要 目的构建脑膜炎奈瑟菌外膜蛋白NspA基因重组子,实现其在大肠杆菌的高效表达。方法提取脑膜炎奈瑟菌标准株基因组DNA,PCR扩增NspA基因,插入表达质粒载体pET-30c中,构建pET-NspA重组子,转化大肠杆菌BL21(DE3),异丙基-β-D-硫代半乳糖苷(IPTG)诱导重组蛋白表达,SDS-PAGE和Western blot检测表达蛋白,镍琼脂糖凝胶纯化NspA融合蛋白。结果获得了脑膜炎奈瑟菌NspA基因的表达重组子,得到NspA诱导表达蛋白并进行了初步纯化。结论成功构建了脑膜炎奈瑟菌NspA基因的表达重组子,实现了该基因在大肠杆菌中的高效表达,为研究该蛋白的免疫学性能、制备抗体和研制预防脑膜炎的疫苗奠定了基础。
