In its 95 paralogous gene families, there is a large outer membrane protein (OMP) family. It includes 32 members. These OMP are important for the diagnosis, protective immunity, pathogenicity of H pylori and so on. They are significantly associated with high H pylori density,the damage of gastric mucosa, high mucosal IL-8 levels and severe neutrophil infiltration. We introduce their research progress on pathogenicity.展开更多
本试验旨在构建贝氏柯克斯体外膜蛋白H(outer membrance protein H,OmpH)的重组表达载体并分析该蛋白的免疫原性,以贝氏柯克斯体九里株为模板,通过PCR方法扩增出含798bp的贝氏柯克斯体的OmpH基因片段,并将其克隆至原核表达载体pQE-30,...本试验旨在构建贝氏柯克斯体外膜蛋白H(outer membrance protein H,OmpH)的重组表达载体并分析该蛋白的免疫原性,以贝氏柯克斯体九里株为模板,通过PCR方法扩增出含798bp的贝氏柯克斯体的OmpH基因片段,并将其克隆至原核表达载体pQE-30,得到重组表达质粒pQE-30/OmpH。经IPTG诱导后,SDS-PAGE结果发现,该重组蛋白大小约为25ku。Western blotting试验结果显示,该方法所诱导产生的重组蛋白具有良好反应原性。展开更多
