摘要
[目的]构建鸡IFN-γ的表达载体。[方法]采用PCR方法从pcDNA-ChIFN-γ重组质粒中扩增得到鸡IFN-γ基因,将目的基因定向克隆至能够在大肠杆菌、昆虫细胞和哺乳动物细胞中表达的pQE trisystem载体内,转化大肠杆菌M15菌株,以IPTG诱导表达8×H is-tag标签蛋白并对其进行纯化。[结果]通过SDS-PAGE检测方法表明,ChIFN-γ基因片段成功表达。[结论]鸡IFN-γ的表达载体成功构建。
[Objective]The aim was to study construction of expression vector of ChIFN-γ gene[Method]Chicken interferon-γ gene was cloned from the recombinant vector pcDNA-ChIFN-γ using PCR method.The fragment of ChIFN-γ was subcloned into pQE trisystem vector that could express in E.coli,insect cells and mammalian cells according to the current open reading frame.The recombinant vector was transformed into M15 bacteria and was induced by IPTG to express 8×His-tag protein which could be used to detect ChIFN-γ.[Result]The results of SDS-PAGE showed that ChIFN-γ protein was expressed successfully.[Conclusion]Construction of expression vector of ChIFN-γ gene was successful.
