摘要
[目的]克隆人Notch信号通路中配体Jagged1基因并进行真核表达。[方法]采用RT-PCR的方法从Hela细胞总RNA中获取Jagged1基因,并克隆至携带FLAG标签的真核表达载体pCMV-Tag4。经酶切、PCR和测序鉴定后,将重组质粒Jagged1-pCMV-Tag4瞬时转染HEK 293T细胞,通过Q-PCR和Western blot检测目的蛋白的表达。[结果]成功构建了真核表达质粒Jagged1-pCMV-Tag4并在HEK 293T细胞中瞬时表达。[结论]Jagged1在HEK 293T细胞中实现瞬时表达,为稳定表达和进一步研究Jagged1/Notch信号通路奠定基础。
[Objective]To clone and express human Notch ligand Jaggedl in eukaryotic cells. [ Methods] Jaggedl gene was amplified from total RNA in Hela cells by RT - PCR, and cloned into eukaryotic expression vector pCMV - Tag4 containing FLAG to construct Jaggedl - pCMV - Tag4. The recombinant plasmid was transiently transfected into HEK 293T cells. Real - time quantitative PCR and Western blot were performed for further confirmation. [ Results ] The eukaryotic expression plasmid Jaggedl -pCMV- Tag4 was constructed successfully and was transfected into HEK 293T cell. [ Conclusion] Jaggedl is ex- pressed in HEK 293T cell which provides a foundation for further investigation of Jaggedl/Notch signaling pathway.
