目的:构建尘螨变应原Der f1 真核表达载体,转染真核细胞并进行蛋白表达。方法:根据Genebank 中Der f1 基因的核酸序
列(AB034946),设计引物,采用PCR 法,从保存的JM109 工程菌中扩增Der f1 编码基因,克隆到真核表达质粒pcDNA3.
1/myc-his A 上,以脂质体法转染CHO 细胞,经G418 筛选,进行稳定表达细胞株的筛选和鉴定。结果:将目的基因Der f1 成功连
接到pcDNA3.1/myc-hisA-Derf1 并转染CHO 细胞,获得稳定表达的CHO 细胞株。结论:成功构建了尘螨变应原Der f1 真核表达
载体,并转染CHO 细胞表达蛋白质。 |

Objective: To construct eukaryotic expressing vector of derf1 gene of dermatophagoides farinae, and transfect CHO
cells for protein expression. Methods: According to the Genebank nucleic acid sequences of Derf1 (No.AB034946), designed primers,
amplified the Der f 1 gene from the preservative engineering bacteria JM109 by PCR, then cloned it into plasmid pcDNA3.1/myc-his A;
and then transfected the plasmid into CHO cells by liposomes and screening the positive cell clone use G418 to express the protein of
Derf1 gene. Results: The Derf1 gene was connected to plasmid pcDNA3.1/myc-hisA and screening into CHO eukaryotic expression cells
successfully. Conclusions: The eukaryotic expression vector of Derf1 was constructed well and got its protein. |
