摘  要:
为了进行抗蜱及蜱传病疫苗的研究,本试验根据GenBank中的镰形扇头蜱组胺结合蛋白(Rhipicephalus haemaphysaloideshistamine bindingprotein,RhHBP)基因cDNA序列,设计一对特异性引物(内含EcoRI/XhoI酶切位点),经RT-PCR扩增了镰形扇头蜱组胺结合蛋白RhHBP的cD-NA,大小为603 bp,将其克隆到pGEM-Teasy中并测序。在去除编码RhHBP信号肽的核苷酸序列后,将其亚克隆到pGEX-4T-1中,构建重组质粒pGEX-4T-1-RhHBP,将该重组质粒转化大肠杆菌BL21,经终浓度为1 mmol/L IPTG诱导其表达,表达的融合蛋白大小为49 ku,以包涵体的形式存在。Western Blot分析表明,该蛋白具有良好的免疫原性。

摘  要:
According to the Rhipicephalus haemaphysaloides histamine binding protein(RhHBP) gene sequence available in GenBank,the specific primers with EcoRI/XhoI site were designed by DNAMAN software.The RhHBP gene fragment was amplified by RT-PCR from genomic RNA and cloned into pGEM-T easy plasmid vector for sequencing.The RhHBP gene is 603bp in length.The gene fragment without the signal peptide was subcloned into vector pGEX-4T-1,and expressed in E.coli BL21 with the induction of 1mmol/L IPTG.The expressed protein had a molecular weight of 49 ku.The Western blot analysis indicated that the protein could react with the serum to RhHBP.
