摘    要:参照猪传染性胸膜肺炎放线杆菌(Actinobacillus pleuropneumoniae,APP)血清1型菌株,设计1对特异性引物,PCR扩增转铁结合蛋白B(tbpB)全基因,克隆到pMD19-T Simple载体中,经测序比较,与参考序列的核苷酸同源性达99.72%。试验将tbpB基因定向克隆到pET-32a( )中,转化BL21(DE3),经诱导后,SDS-PAGE结果显示转铁结合蛋白B得到表达,Western blot检测呈阳性。

关 键 词:  胸膜肺炎放线杆菌  转铁结合蛋白B  克隆  表达

Abstract:The tbpB gene from serotypc 1 strain of Actinobacillus pleuropneumoniae was amplified by PCR.The amplified DNA fragment was cloned into pMD19-T simple,and sequenced.The result showed that the gene was 1 812 bp in length and shared 99.72% sequence identity with that of standard strains.The gene was subcloned into in pET-32a( )and successfully expressed in Escherichia coli BL21(DE3)after induced,which was confirmed by Western blot.
Keywords:pig  Actinobacillus plcuropneumoniac  tbpB  cloning  expression
