摘要(Abstract):
通过PCR方法克隆草鱼(Ctenopharyngodon idellus)NEDD4结合蛋白基因1(简称CiN4BP1)的开放阅读框(ORF)序列,将扩增产物与pET-32a(+)表达载体相连接,构建原核表达载体pET-N4BP1,对重组质粒进行酶切和测序鉴定,然后将其导入大肠杆菌BL21(DE3),经异丙基-β-D-硫代半乳糖苷(IPTG)诱导,检测该蛋白表达情况。SDS-PAGE分析表明,在温度为37℃,IPTG浓度为0.06 mmol/L,诱导时间为4 h时,N4BP1重组融合蛋白的表达量最高,蛋白分子质量为40.2 ku,与软件预测值大小相符,该蛋白主要以包涵体形式表达。利用His Trap HP亲和柱纯化目的蛋白;Western blot分析表明,N4BP1融合蛋白能与鼠抗His-tag单克隆抗体发生特异性反应,说明该表达的蛋白为目的蛋白。
