摘  要:
为获得A亚群禽白血病病毒(ALV-A)env基因的表达产物,以ALV-A AH10毒株病毒RNA为模板,通过反转录PCR扩增得到env基因,将其克隆到转移载体p Fast Bac1中,转化DH10Bac感受态细胞,获得重组穿梭质粒r Bacmid-env A,r Bacmid-env A转染昆虫细胞Sf9,获得重组杆状病毒。间接免疫荧光试验(IFA)和免疫印迹试验(Western-blot)结果显示,重组蛋白可与抗ALV-A抗体发生特异性反应,重组蛋白分子大小约为90 000,与预期大小相符,表明env基因在Sf9细胞中获得了良好表达。

摘  要:
To abtain the expression product of subgroup A avian leukosis virus env gene,the env gene amplified from subgroup A avian leukosis virus strain AH10 was cloned into transfer vector p Fast Bac1 and cloned into the shuttle vector Bacmid by transferred into DH10 Bac competent cell. The recombinant shuttle plasmid r Bacmid-env A was then transfected into Sf9 cells to generate recombinant virus. The results of indirect immunofluorescence assay(IFA) and western blot showed that the recombinant protein could be recognized specifically by the polyclonal antibody against ALV-A with the molecule weight about 90 000,which was consistent with the expected,and all the results indicated that the env gene was expressed well in Sf9 cells.
