  • A surface antigen hemagglutinin - neuraminidase ( hn ) gene of the ndv b95 strain , was selected to study as target gene . referred to the reported sequence , rwo primers were designed and synthesized . hn gene of ndv b95 strain was amplified by rt - pcr , the pcr products were checked by agrose gel electrophoresis and purified by agrose gel fraction method
    为此,从澳大利亚某大学兽医病理系引进一株ndv热稳定性天然弱毒b95株,并选取其表面抗原血凝素?神经氨酸酶的编码基因为目的基因,根据国外已发表的序列,设计一对引物,利用rt - pcr技术扩增出了ndvb95株hn基因。
  • Major difference of hn proteins lies in no . 18 - no . 75 amino acid residues on n - terminal which includes three active sites of hn protein . the influence on biological action , caused by the difference of hn protein , is needed to study further . hn gene has only four glycosylation sites , which is 1 or 2 less on amount than that of other strains . so , this difference can be take on as a natural mark of ndv b95 strain furthermore , the fragment encoding hn gene was excised from the positive clone pgem - hn with sail and saci enzyme , and purified by agrose gel fraction method . then the fragment was subcloned into the pet - 28c expressing vector digested by sail and saci restriction enzyme
    作者将正确的重组克隆质粒pgem - hn用saii 、 saci双酶切,电泳回收目的片段,将其亚克隆到经saii 、 saci双酶切处理的pet - 28c中,转化大肠杆菌tgi感受态细胞,得到的转化子经pcr鉴定和酶切分析,筛选出符合阅读框的重组子,构建成重组表达质粒pet - hn ,并在大肠杆菌bl _ ( 21 ) ( de _ 3 )宿主菌中成功地表达了含目的蛋白的融合蛋白,融合蛋白的分子量约66kd ,加入iptg诱导8h后,蛋白表达几乎达到最高水平。
