野生型及突变型人血管内皮生长因子A真核表达载体的构建与鉴定
Journal of Bengbu Medical College(2013)
Abstract
目的:构建人野生型和c.454C>T突变型血管内皮生长因子A(VEGFA)真核表达载体。方法:采用反转录聚合酶链反应扩增人VEGFA基因,用限制性核酸内切酶BglⅡ和SalⅠ双酶切后连接真核表达载体pEGFP-N1,构建野生型VEGFA真核表达载体(野生型pEGFP-VEGFA),通过双酶切和测序进行鉴定。采用定点诱变PCR技术构建c.454C>T突变型人VEGFA真核表达载体(突变型pEGFP-VEGFA),同样通过双酶切和测序进行鉴定。结果:野生型和突变型pEGFP-VEGFA被双酶切为4 697 bp和1 251 bp两条条带。测序结果证实野生型pEGFP-VEGFA VEGFA序列与GenBank公布的VEGFA mRNA序列完全一致,突变型pEGFP-VEGFA除第454位碱基C被T替代以外,其余序列与野生型完全一致。结论:成功构建了野生型和突变型pEGFP-VEGFA,为下一步研究VEGFA基因功能提供参考。
