摘要:

试验旨在扩增羊口疮病毒(Orf virus,ORFV)ORF059基因并进行真核表达。提取羊ORFV HCE弱毒株基因组为模板,参照GenBank上ORF059的基因序列,利用DNAMAN设计引物,应用PCR扩增ORF059目的片段,凝胶回收后将其连入pEGFP-N1质粒,构建重组质粒pEGFP-ORF059-N1,测序正确后瞬时转染NIH3T3细胞,应用荧光显微镜观察,Western blotting鉴定融合蛋白的表达。结果表明,ORF059基因片段大小为1 005 bp;重组质粒pEGFP-ORF059-N1构建正确;转染pEGFP-ORF059-N1的NIH3T3细胞有明显的绿色荧光;表达的融合蛋白大小约为64 ku。本试验结果为进一步研究ORF059的作用机理奠定了基础。

Abstract:

The study was aimed to clonie and express ORF059 gene of Orf virus (ORFV).The genome of ORFV HCE attenuated vaccine strain was extracted and used as the template.Based on the referenced gene sequences of ORF059 gene on GenBank,the specific primers were designed,the fragment of ORF059 gene was amplified by PCR.After being purified,ORF059 gene was inserted into pEGFP-N1 vector to construct recombinant plasmid pEGFP-ORF059-N1.After being sequenced,the recombinant plasmid pEGFP-ORF059-N1 was transfected into NIH3T3 cells with liposomes.The expression of fusion protein was identified by the fluorescence microscope observation and Western blotting.The results showed that the ORF059 gene was 1 005 bp.The recombinant plasmid pEGFP-ORF059-N1 was constructed correctly.Green fluorescence could be observed in NIH3T3 cells transfected by pEGFP-ORF059-N1 under the fluorescence microscope.The expressed fusion protein was about 64 ku.The results laid a foundation for the further research on the mechanism of ORF059.
