| 摘 要： | 基于海口市动物基因工程重点实验室获得的牛乳状瘤病毒13型(BPV-13)基因组序列信息(GenBank登录号:KM258443.2),以基因组为模板,扩增E5基因片段,将其连入pEGFP-N1质粒,构建重组质粒pEGFP-E5-N1,测序正确后瞬时转染HEK293细胞,应用荧光显微镜、流式细胞仪、Western blotting 鉴定融合蛋白的表达。结果显示,E5片段大小为135 bp;重组质粒pEGFP-E5-N1构建正确;荧光显微镜下观察转染重组质粒pEGFP-E5-N1的HEK293细胞,可见明亮的绿色荧光;流式细胞术分析结果显示,转染重组质粒pEGFP-E5-N1 48 h后,约55.59% 的细胞表达绿色荧光蛋白;Western blotting结果表明,表达的融合蛋白大小约为32 ku。本试验结果为下一步研究E5基因的作用机理奠定了基础。

| Abstract: | The PCR technology was used to amplify the E5 gene according to the genome sequence of bovine papillomavirus type 13 (BPV-13) Hainan strain with the GenBank accession number KM258443.2.Then it was ligated into pEGFP-N1 vector.The recombinant plasmid pEGFP-E5-N1 was transfected into HEK293 cells with liposomes by transient transfection.The expression of fusion protein was identified by fluorescence microscope, flow cytometry and Western blotting.The results showed that the E5 gene was 135 bp with the 100% homology with the sequence deposited in GenBank.Bright green fluorescence could be seen in HEK293 cells transfected by pEGFP-E5-N1.The expressed fusion protein was about 32 ku.This experiment laid the foundation for further study of the functions of E5 gene in eukaryotic cells. |
