| 摘 要： | 构建含人VEGF165基因的重组真核表达质粒,并对其表达蛋白特性进行初步分析。将合成的VEGF165基因序列克隆至pCR2.1-TOPO载体,测序鉴定证实基因碱基序列无误后,再克隆至真核表达载体pcDNA3.1(+),构建成pcD-NA3.1(+)-VEGF165重组质粒。利用DNAstar软件分析基因序列并翻译成氨基酸序列,再用ExPASy protscale和Protean软件分析其疏水特性、蛋白二级结构。经基因测序、酶切鉴定和PCR鉴定证实pcDNA3.1(+)-VEGF165重组质粒构建成功。Ex-PASy protscale和Protean软件分析表明VEGF165蛋白具有较好的水溶性。本研究为VEGF165的基因治疗应用和VEGF165蛋白直接治疗勃起功能障碍奠定了基础。

| Abstract: | It was to construct the pcDNA3.1(+)-VEGF165 expression vector and analyze the expressed protein.VEGF165 gene was cloned to pCR2.1-TOPO vector and then cloned into the vector pcDNA3.1(+)after sequencing.Two softwares ExPASy protscale and Protean were used to analyze the hydrophobic character and secondary structure of VEGF165 protein.Results indicated that pcDNA3.1(+)-VEGF165 was successfully constructed and confirmed by gene sequencing and PCR identification.Analysis with ExPASy protscale and Protean showed... |
