摘要 目的克隆结核分枝杆菌基因组携带的两组GroEL基因,即GroEL1和GroEL2,它们分别编码热休克蛋白HSP60(cpn60.1)和HSP65(cpn60.2),并构建真核表达质粒。方法用带有EcoR I和Xba I酶切位点的特异性引物,从结核杆菌H37Rv株中PCR扩增两组GroEL基因,构建重组真核表达质粒pCDNA3.1-GroEL1和pCDNA3.1-GroEL2,并进行酶切和测序鉴定。结果成功克隆了结核分枝杆菌两组GroEL基因,酶切鉴定pCDNA3.1-GroEL1和pCDNA3.1-GroEL2构建成功,经DNA测序证实,载体上插入的序列与GenBank公布的序列一致。结论获得了结核分枝杆菌GroEL1和GroEL2基因,成功地构建了含GroEL1和GroEL2基因的真核表达质粒,为研究其作为核酸疫苗在免疫学方面作用提供材料。
