摘要
目的: 拟获得编码IP10 (IFNγinducible protein10) 和Crg2 (cytokine responsive gene2) 的cDNA 序列。方法: 针对IP10 和Crg2 的cDNA序列设计相应引物, 通过反转录PCR技术, 分别从用IFNγ及TNFα处理的人成纤维细胞及Balb/c 小鼠肝脏中, 扩增出编码IP10 和Crg2 的全基因序列, 并将其克隆入载体pUC19及pGEM3Zf (+ ) 中, 通过酶切及序列测定鉴定重组载体。结果: 经序列测定证实, 重组载体含有正确地分别编码IP10 及Crg2 的cDNA序列。结论: 获得的阳性克隆分别含有306bp 和314bp 的重组片段, 为进一步对其生物学活性和配体进行研究奠定了基础。
Aim: To obtain cDNA encoding human IP 10 and murine Crg 2 Methods: The cDNA of IP 10 and Crg 2 genes were amplified by RT PCR from cultured human fibroblasts and Balb/c mouse liver treated with IFN γand TNF α, respectively Are recombinant fragment of 306bp and 314bp were cloned into plasmids pUC19 and pGEM3Zf(+), respectively Identified by endonucleases digestion and sequencing Results: Sequencing comfirmed that IP 10 and crg 2 gene frag ments existed recombinants Conclusion: Recombinant human IP 10 and murine crg 2 gene clones laid the foundation for further research on biological activities and ligands of IP 10/Crg 2
