摘要:
为了建立蓝舌病(BT)的血清学诊断方法,本研究利用原核表达的蓝舌病病毒(BTV)血清型12型VP7纯化蛋白免疫BALB/c小鼠,制备2株单克隆抗体(MAb),分别命名为BTV-2D10和BTV-4H7。IFA试验表明,2株MAb均能与BTV 24个血清型发生特异性反应,而与茨城病病毒(IBAV)、中山病病毒(CV)、赤羽病病毒(AKAV)、牛病毒性腹泻病毒(BVDV)、牛传染性鼻气管炎病毒(IBRV)、牛轮状病毒(BRV)、牛肠道病毒(BEV)、牛呼肠孤病毒(RV)及口蹄疫病毒(FMDV)无交叉反应,表明2株MAb均为BTV群特异性抗体。采用重组表达的VP7蛋白作为包被抗原建立的竞争ELISA方法证明,BTV-4H7 MAb对不同血清型BTV阳性血清具有良好的阻断效果,而对AKAV、IBAV、BRV和FMDV阳性血清无阻断作用。本研究建立的竞争ELISA方法与IDEXX公司的试剂盒检测包括65份已知背景血清和322份采自广西省的山羊血清样品,检测结果符合率分别达100 %和98 %。该竞争ELISA方法的建立为BTV抗体的监测提供了安全、快速、准确的技术手段。
Abstract:
To development ELISA method for detecting antibodies against bluetongue virus (BTV), two monoclonal antibodies (MAbs) against BTV12 VP7 protein were produced by fusing SP2/0 myeloma cells with spleen cells of BALB/c mice immunized with purified recombinant BTV12 VP7 protein and screened by ELISA coated by BTV12. The indirect mmunofluorescence assay showed that both of the MAbs were reacted positive with 24 serotypes of BTV, but not reacted with other related viruses. These results indicated that the two MAbs were group-specific antibodies to BTV. Furthermore, the competitive ELISA with the MAbs was established and the MAb 4H7 had the group specific blocking effect. Clinical sample detectionss showed the method had 100% agreement with IDEXX kit to detect of 65 known background serum samples and 98% agreement with IDEXX kit to detect 322 serum samples from Guangxi. Therefore, the competitive ELISA assay established in this study provided a low-cost, effective, quick and accurate method for the detection of antibodies against BTV.
