【摘要】：目的:比較引入六種不同Kozak序列口蹄疫DNA疫苗的表達水平及免疫效果。方法:在口蹄疫DNA疫苗抗原編碼基因VP1起始位點引入6種不同的Kozak序列(KZ1～KZ6),插入真核表達載體pVAX1,制備口蹄疫DNA疫苗,對6-8周齡BLAB/C小鼠進行免疫,用酶聯(lián)免疫吸附試驗(enzyme_linked immunosorbent assay,ELISA),分析實驗動物外周血抗VP1的抗體效價;同時插入帶有綠色熒光蛋白的融合表達載體pEGFP-N1,構(gòu)建6種體外表達質(zhì)粒,轉(zhuǎn)染HeLa細胞,進行瞬時表達并分析體外表達水平。結(jié)果:引入Kozak序列KZ6的疫苗質(zhì)粒pKV6接種動物后產(chǎn)生的免疫抗體水平高于其它組;相應(yīng)的體外表達質(zhì)粒pKG6轉(zhuǎn)染HeLa細胞后體外表達水平辦高于其它組。結(jié)論:引入Kozak序列KZ6(帶有三聯(lián)密碼AAA)的口蹄疫DNA疫苗,能最有效地增加疫苗的蛋白表達量,并達到最佳的免疫效果。
[Abstract]:Objective: To compare the expression level and immune effect of six different Kozak sequences of foot-and-mouth disease DNA vaccine. Methods: the introduction of 6 different Kozak sequences in the DNA FMD vaccine antigen encoding gene VP1 codon (KZ1 ~ KZ6), inserted into the eukaryotic expression vector pVAX1, preparation of FMD DNA vaccine to immunize 6-8 BLAB/C mice by enzyme-linked immunosorbent assay (enzyme_linked immunosorbent, assay, ELISA) antibody the titer of anti serum VP1 analysis of experimental animal outside; while inserting fusion with green fluorescent protein expression vector pEGFP-N1, construct 6 kinds of in vitro expression plasmid transfected into HeLa cells for transient expression analysis and in vitro expression. Results: the antibody level of Vaccine Plasmid pKV6 with Kozak sequence KZ6 was higher than that of other groups after inoculation, and the expression level of corresponding plasmid pKG6 in vitro was higher than that of other groups. Conclusion: the introduction of Kozak sequence KZ6 (DNA with triple AAA) can effectively increase the protein expression of vaccine and achieve the best immune effect.
