摘要: 目的:克隆小鼠干扰素γ(IFN-γ)编码区cDNA序列并构建含Egr-1启动子的辐射诱导表达质粒pIRESEgr-IFNγ。 方法:利用逆转录多聚酶链反应(RT-PCR)法,以小鼠脾细胞mRNA为模板,扩增获得全长IFNγcDNA,与pGEMT载体连接做全自动测序,并利用基因重组技术构建含Egr-1启动子的辐射诱导表达质粒pIRESEgr-IFNγ。 结果:经测序证实获得的小鼠IFNγ cDNA序列与文献报道完全一致,并构建了含Egr-1启动子的辐射诱导表达质粒pIRESEgr-IFNγ。结论:成功克隆了小鼠IFNγ的cDNA序列,构建了辐射诱导表达质粒pIRESEgr-IFNγ。

Abstract: Objective To clone the sequence of the cDNA of mouse interferon-gamma coding area and construct radiation-inducible expression plasmid pIRESEgr-IFNγ containing Egr-1 promoter. Methods With the technique of RT-PCR, mouse splenocyte mRNA was used as template to obtain full length mouse IFNγ. The pGEMT-IFNγ was sequenced automatically and radiation-inducible expression plasmid pIRESEgr-IFNγ containing Egr-1 promoter was constructed with gene recombinant technique. Results The sequencing proved the cloned mouse IFNγ cDNA to be completely identical with that reported in the literature and the radiation-inducible expression plasmid pIRESEgr-IFNγ containing Egr-1 promoter was constructed successfully. Conclusion Mouse IFNγ cDNA was cloned and the radiation-inducible expression plasmid pIRESEgr-IFNγ containing Egr-1 promoter was constructed successfully.
