目的:

构建可涂布于介入器械的人血管内皮生长因子(VEGF)真核表达载体。

方法:

根据人VEGFA(NM_001025366)目的序列设计引物制备目的基因及载体,双酶切载体pIRES2-ZsGreen1和目的基因homo VEGFA进行连接后转化入大肠杆菌,构建质粒pIRES2-ZsGreen1-homo-VEGFA并测序鉴定。

结果:

目的基因VEGFA已连接到载体pIRES2-ZsGreen1,大小约1400 bp,与人VEGFA(NM_001025366)目的序列比对结果一致,未见变异。质粒pIRES2-ZsGreen1-homo-VEGFA构建成功。

结论:

成功构建重组人血管内皮生长因子真核表达载体,可用于涂布介入器械表面进行下一步实验。

Objective:

To construct the eukaryotic expression vector for recombinant vascular endothelial growth factor (VEGF) for coating interventional device.

Methods:

The primer was designed to prepare the target gene and vector according to the sequence of human VEGFA (NM_001025366) , and then was connected and transformed to E. coli after double digestion of homo VEGFA and pIRES2-ZsGreen1 plasmids. Then the vector pIRES2-ZsGreen1-homo-VEGFA was constructed and identified.

Results:

The target gene, VEGFA, has been connected to the vector pIRES2-ZsGreen1, which was a 1400 bp plasmid. The sequence alignment was consistent with that of human VEGFA (NM_001025366) and no mutation was found. Plasmid pIRES2-ZsGreen1-homo-VEGFA was successfully constructed.

Conclusions:

The eukaryotic expression vector pIRES2-ZsGreen1-homo-VEGFA is successfully constructed, and can be used to coat interventional device.
