摘要 目的:克隆小鼠CXCR4基因并建立其慢病毒表达系统。方法:设计合成PCR引物,从小鼠骨髓有核细胞来源的cDNA中扩增并克隆小鼠CXCR4基因的编码区。构建CX-CR4-IRES-GFP表达单元后通过转染细胞,观察GFP的表达证实其表达效能。然后建立慢病毒表达载体,包装慢病毒后感染培养的细胞,用流式细胞术分析其在被感染的细胞中的表达。结果:成功扩增了小鼠CXCR4基因的编码区。克隆入质粒载体后经DNA序列测定证实了其序列。通过转染细胞和流式细胞术以及荧光显微镜观察证实了CXCR4-IRES-GFP的表达效能。成功构建了CXCR4慢病毒表达载体,感染细胞后经流式细胞术分析,证实被感染的细胞可以表达小鼠CX-CR4。结论:成功扩增、克隆了小鼠CXCR4基因,并成功建立起其慢病毒表达系统,为后续的基础和应用研究奠定了基础。
