【摘要】: 本論文以人乳頭瘤病毒58型(human papillomavirus type 58,HPV58)的晚期蛋白L1基因和晚期蛋白L2基因分別表達(dá)的晚期蛋白HPV58 L1和HPV58 L2作為研究對(duì)象,在體外將這兩種蛋白組裝成為病毒樣顆粒VLP(virus like praticles)。我們將本實(shí)驗(yàn)室已構(gòu)建的pRSETB-HPV58 L1和pRSETB-HPV58 L2整合型質(zhì)粒分別轉(zhuǎn)化進(jìn)BL21大腸桿菌中,獲得穩(wěn)定表達(dá)HPV58 L1蛋白和HPV58 L2蛋白的重組菌株;然后利用IPTG誘導(dǎo)表達(dá)這兩種蛋白;純化這兩種蛋白;并復(fù)性了HPV58 L1蛋白;然后利用這兩種蛋白組裝成VLP。研究表明在現(xiàn)有的實(shí)驗(yàn)條件下原核系統(tǒng)表達(dá)的HPV58 L1蛋白可以在體外單獨(dú)組地裝成VLP,而HPV58 L2蛋白則不能與HPV58 L1蛋白共同組裝成VLP.。
[Abstract]:In this study, HPV58 L1 and HPV58 L2, which were expressed in late protein L1 and L2 gene of human papillomavirus 58 papillomavirus type 58 / HPV58, respectively, were used to assemble these two proteins into virus-like particles VLP(virus like praticlesus in vitro. We transformed pRSETB-HPV58 L1 and pRSETB-HPV58 L2 integrative plasmids constructed in our laboratory into BL21 Escherichia coli, and obtained the recombinant strain expressing HPV58 L1 protein and HPV58 L2 protein stably, then expressed these two proteins by IPTG induction, and purified the two proteins. HPV58 L1 protein was refolded and then assembled into VLP using these two proteins. The results showed that the HPV58 L1 protein expressed in prokaryotic system could be assembled into VLP alone in vitro, while HPV58 L2 protein could not be assembled with HPV58 L1 protein.
