| 摘 要： | 目的制备柯萨奇病毒B3(coxsackievirus B3,CVB3)的多克隆抗体。方法针对CVB3基因的VP1区设计特异性引物,RT-PCR扩增VP1基因并将其克隆到pGEX-6p-1中,经IPTG诱导表达后,以GST-VP1融合蛋白作为抗原免疫新西兰大白兔,制备多克隆抗体。采用ELISA、Western blot以及间接免疫荧光检测多克隆抗体的效价和特异性。结果 ELISA检测血清的效价不低于1∶64 000,Western blot和间接免疫荧光显示该抗体具有良好的特异性。结论成功制备了效价较高的CVB3多克隆抗体,可应用于CVB3蛋白的检测。 |

| Abstract: | Objective To prepare polyclonal antibody against coxsackievirus B3(CVB3).Methods Specific primers which based on VP1 gene of CVB3 were designed,VP1 gene amplified by RT-PCR was cloned into pGEX-6p-1.High titer polyclonal antiserum was obtained by immunizing New Zealand rabbits with GST-VP1 fusion protein which was induced by IPTG.Then titer of the polyclonal antibody was determined by ELISA and specificity of it was tested by Western blot and indirect immunofluorescence assay.Results The titer of antiserum ... |
