摘要: 试验采集新疆细毛羊皮肤组织,提取RNA,采用反转录聚合酶链式反应(RT-PCR)技术扩增出KAP6.1基因,并通过DNA重组技术将该基因片段重组于pEGFP-C2真核表达载体上,构建pEGFP-C2-KAP6.1重组质粒,并进行PCR、酶切鉴定。结果表明,本试验成功构建了新疆细毛羊的pEGFP-C2-KAP6.1真核表达重组质粒,为进一步研究该基因所编码的蛋白与毛品质的关系,以及培育超细羊毛等经济性生物学性状相互关系提供理论依据。

Abstract: In the experiments, collected the skin tissues of Xinjiang fine-wool sheep, extracted RNA, used reverse transcription-polymerase chain reaction (RT-PCR) to amplify the KAP6.1 gene, and the recombination of the gene recombined into the pEGFP-C2 eukaryotic expression vector through the recombinant DNA technique, constructed the pEGFP-C2-KAP6.1 recombinant plasmid, then did the identification of PCR and enzyme digestion. The results showed that we successfully constructed the pEGFP-C2-KAP6.1 eukaryotic expression recombinant plasmid of Xinjiang fine-wool sheep. In order to further study the relationship of the protein encoding by the gene and the wool qualities, and provide a theoretical basis for the cultivation of economy biological characteristics interrelationship of superfine wool.

Key words: Xinjiang fine-wool sheep; pEGFP-C2 vector; KAP6.1 gene; eukaryotic expression
