摘要: [目的]克隆、表达牦牛源多杀性巴氏杆菌(Pm)外膜蛋白基因H(ompH)并鉴定其抗原性.[方法]扩增牦牛源多杀性巴氏杆菌去信号肽的ompH基因,构建原核表达载体pET28a - ompH,转化大肠杆菌BL21( DE3)并诱导表达,通过SDS-PAGE鉴定表达目的蛋白,利用Western blot检测该蛋白的抗原性.[结果]成功克隆、构建了牦牛源多杀性巴氏杆菌去信号肽的pET28a - ompH原核表达载体.诱导表达蛋白约38 kDa,Western blot检测重组蛋白具有良好的抗原性.[结论]ompH基因的成功表达为重组OmpH蛋白的血清学检测方法的建立、多克隆抗体的制备及疫苗的研制奠定了基础.
