摘要 目的 构建真核表达质粒PcDNA3.1(+)-带有Vasostatin自身信号肽的Calreticulin(120~180aa)并了解其在真核细胞内的表达。方法 将带有Vasoatatin自身信号肽的Calreticulin(120~180aa)的RT-PCR产物克隆至peDNA3.1(+)真核表达载体上,经酶切鉴定及测序分析证明构建成功后,以脂质体介导法转染真核细胞COS-7,并行Western法检测。结果 成功构建了真核表达质粒PeDNA3.1(+)-带有Vasostatin自身信号肽的Calreticulin(120~180aa),将之转染体外的真核COS-7细胞后,在其上清液中,检测到目的蛋白质。结论 该构建的质粒可在真核细胞中表达目的蛋白质,这为基因治疗视网膜新生血管类病奠定了一定基础。 Objective To clone human vasostatin (120 - 180 aa) gene to construct the recombined plasmid pcDNA3.1 ( + )-va-sostatin ( 120 - 180 aa) and observe its expression in COS-7. Methods The recombined plasmid encoding vasostatin ( 120 - 180 aa) firstly was cloned into eukaryotic expressive vector of pcDNA3.1 ( + ) to verify its successful construction by enzyme digestion and sequence analysis. Then COS-7 cells were transfected mediated by liposeme and detected by Western blotting. Results pcDNA3. 1 ( + )-vasostatin ( 120 - 180 aa) constructed successfully transfected COS-7 to detect target protein in the supernatant. Conclusions The recombined plasmid constructed could successfully express the vasostatin ( 120 - 180 aa) protein in transfected eukaryotic cells COS-7, which establish a certain foundation for gene treatment of retina neovascularisation disease.
