A cDNA clone for human immune interferon (IFN-gamma) gene sequences, plasmid p69, was used to chromosomally map the IFN-gamma gene by detecting human IFN-gamma gene sequences in DNA isolated from human-rodent somatic cell hybrids. We were able to map the IFN-gamma gene by correlating the human chromosomes present in these hybrids with the human specific 8.8 and 2.0 kilobase pair fragments produced by EcoRI digestion of genomic DNA. Southern blot analysis of 37 hybrid cell lines indicated that the gene for IFN-gamma was on human chromosome 12. A hybrid containing a portion of chromosome 12 localized the IFN-gamma gene to the p1205 leads to qter region.
利用人免疫干扰素(IFN-γ)基因序列的cDNA克隆质粒p69,通过检测从人-啮齿动物体细胞杂种中分离出的DNA中的人IFN-γ基因序列,对IFN-γ基因进行染色体定位。我们通过将这些杂种中存在的人类染色体与基因组DNA经EcoRI酶切产生的8.8和2.0千碱基对的人特异性片段相关联,从而对IFN-γ基因进行定位。对37个杂种细胞系的Southern印迹分析表明,IFN-γ基因位于人类12号染色体上。一个含有12号染色体一部分的杂种将IFN-γ基因定位到了p1205至qter区域。
