摘要
通过T-A克隆技术,成功地构建了克隆载体PMD-18T-CDVF,用KpnI和BamHI双酶切克隆质粒PMD-18T-CDVF后,回收F基因,并将此基因定向克隆至相同双酶切回收后的pcDNA3.1真核表达载体中,获得重组质粒pcDNA3.1-CDVF。经DNA测序、限制性内切酶分析和PCR鉴定,证实成功地构建了重组质粒,从而为研究犬瘟热新型疫苗奠定了基础。
The clone vector PMD-18T-CDVF with fusion gene of canine distemper virus isolated from a mink was successfully constructed by T- A clone technique and was digested with restriction enzyme of Kpn I and BamH I. The F gene was cloned into eukaryotic expression vectorpcDNA3.1. Finally a recombinant plasmid named pcDNA3.1-CDVF was constructed and identified by PCR, restriction enzyme analysis and sequencing.
