人CD200基因克隆及pcDNA3-CD200表达质粒的构建
Cloning of human CD200 gene and construction of expression plasmid pcDNA3-CD200
【摘要】 目的 :克隆人 CD2 0 0基因并构建 pc DNA3- CD2 0 0表达质粒。方法 :采用逆转录聚合酶链式反应(RT- PCR)法 ,从用 2 0 0 μg Con A刺激 6 2 h后的正常人外周血白细胞中扩增出 CD2 0 0基因 ,与 p MD18T载体连接后 ,做全自动 DNA测序 ,并用亚克隆的方法构建 pc DNA3- CD2 0 0表达质粒。结果 :从正常人外周血白细胞扩增的人 CD2 0 0基因与 Gen Bank中人 CD2 0 0序列 (NM 0 0 5 94 4 )完全相同。结论 :成功地克隆人 CD2 0 0基因并构建了 pc DNA3- CD2 0 0表达质粒。
【Abstract】 Objective To clone the human CD200 gene and to construct the expression plasmid pcDNA3-CD200. Methods The CD200 gene was obtained with the technique of RT-PCR from human peripheral white cells at 62 h after stimulation with 200 μg Con A.With automatic sequencing of pMD18T-CD200, the pcDNA3-CD200 recombinant plasmid was constructed by subclone, CD200 gene was obtained from human peripheral white cell. Results The obtained CD200 gene was completely consistent with the human CD200 sequence in GenBank (NM 005944). Conclusion The human CD200 gene is successfully cloned and pcDNA3-CD200 recombinant plasmid is constructed.
