| 摘 要： | 本研究根据已经发表的布氏杆菌基因序列,选择种间序列极为保守的保护性抗原L7/L12、OMP31基因,依此进行PCR扩增,利用引物上设计好的限制性内切酶酶切位点进行基因重组,构建了PME290-SDLOmp高效表达载体,并转化绿脓杆菌(PAK/2pfs),通过培养得到了表达产物,对表达产物进行SDS-PAGE和Western Blot鉴定,结果符合预期。本项研究为进一步开展布氏杆菌亚单位疫苗的研制奠定了基础。

| Abstract: | In this study we carried out gene cloning and fusion expression according to the published gene sequence.We chose the protective antigens L7/L12 and OMP31 which were both extremely conserved sequences between species and amplify with PCR technology.We used the restriction sites designed on the primer carrying on gene recombination.We constructed the effective express vector PME290-SDLOmp.We transformed competence(PAK/2PFS)with constructed vector.After expansion of the bacteria we obtained the expression pro... |
