将狂犬病病毒糖蛋白cDNABglⅡ(1.67kb)片段分别正向插入pmMT-1BglⅡ位点和pMT010/A+BamHI位点,构建重组质粒pmMT-Rgp和pMT010/A+-Rgp,通过磷酸钙共沉淀法转染BHK-21细胞,经PCR、打点杂交及ELISA检测,证明糖蛋白基因发生了整合并获得表达。以该表达载体给小鼠肌肉内注射2~3次,采其注射前、后双份血清,经ELISA检测证明,注射了表达载体的小鼠,血清中病毒特异性抗体明显升高,表明狂犬病病毒糖蛋白cDNA在小鼠体内表达后,刺激机体产生了抗该糖蛋白特异性抗体
Rabies virus glycoprotein cDNABgl Ⅱ (1.67kb) fragment was inserted into the pmMT-1BglⅡ site and pMT010 / A + BamHI site respectively, and the recombinant plasmids pmMT-Rgp and pMT010 / A + -Rgp were constructed and transfected into BHK by calcium phosphate coprecipitation -21 cells by PCR, dot blot hybridization and ELISA test to prove that the glycoprotein gene integration and expression. Mice were intramuscularly injected with this expression vector for 2 or 3 times. Before and after injection, duplicate sera were collected and tested by ELISA. The mice injected with the expression vector had a significantly higher serum specific antibody, indicating that rabies Expression of viral glycoprotein cDNA in mice stimulates the body to produce antibodies specific to the glycoprotein
