摘要
目的:TIPE2[Tumor necrosis factor(TNF)-αinduced protein 8-like 2(TNFAIP8L2),TIPE2]慢病毒载体的构建及病毒包装。方法:首先构建带有3×FLAG标签的pCDNA3.1-3×FLAG-TIPE2质粒,确认表达后再将标签连同TIPE2序列一起克隆入pCDH-CMV-MCS-EF1-Puro慢病毒表达载体,然后与pMD2.G、psPAX2共转染293T细胞并收获上清,进一步用含病毒颗粒的上清感染PLC/PRF/5及HEK293T细胞,Western blot检测感染后TIPE2蛋白表达情况。结果:pCDNA3.1-3×FLAGTIPE2及pCDH-CMV-MCS-EF1-Puro-TIPE2质粒构建成功,并能最终产出具有感染性的病毒颗粒。结论:成功构建了TIPE2慢病毒载体并获得具有感染性的病毒颗粒,为进一步研究TIPE2功能提供了有力的支持。
Objective:To package lentivirus carrying human TIPE2 (Tumor necrosis factor (TNF)-ct induced protein 8-like 2 (TNFAIP8L2), TIPE2) gene. Methods: The human TIPE2 gene was cloned into pDNA3. 1-3 x FLAG vector to generate pCDNA3.1- 3× FLAG-TIPE2 plasmid, after sequencing, 3× FLAG-TIPE2 fragment was inserted into pCDH-CMV-MCS-EF1-Puro lentiviral vector. The pCDH-CMV-MCS-EFI-Puro/3× FLAG-TIPE2 plasmids were co-transfected with pMD2. G,psPAX2 plasmids into HEK293T cells to harvest infectious virus particles, followed by infecting PLC/PRF/5 and HEK293T cells. Results: The TIPE2 expressing lentiviral vector was constructed successfully, and finally got infectious virus particles. Conclusion: The human TIPE2 recombinant lentiviral vector was successfully constructed and packaged.
