摘要:
应用RT-PCR技术扩增了鸡传染性法氏囊病病毒(IBDV)分离株JS7的VP3基因,并进行了分子特征分析和原核表达。结果显示,JS7的VP3基因的关键氨基酸位点上表现为981P、990A、1005A,既有致弱毒株的990A,又有vvIBDV毒株的981P和1005A,在遗传进化和同源性分析上,JS7更接近于vvIBDV参考株;VP3基因在IPTG的诱导下,在pET-28a系统中成功表达出32 ku的产物,western-blot检测发现,该表达产物与鸡抗IBDV多抗血清发生反应。说明JS7-VP3成功表达并具有良好的免疫原性。这为进一步研究IBDV特异性的检测方法的建立以及VP3在IBDV致病性中的进一步研究奠定了基础。
