摘要: 本研究旨在制备山羊支原体山羊肺炎亚种(M.capricolum subsp.capripneumoniae, Mccp)的单克隆抗体并筛选与抗体结合的抗原表位。试验用甲醛灭活的Mccp免疫BALB/c小鼠,运用传统的细胞融合技术进行融合获得杂交瘤细胞,亚克隆,制备单克隆抗体腹水,采用酶联免疫技术(ELISA)和免疫印迹(Western blotting)技术鉴定单克隆抗体的特异性及胶内酶切鉴定与抗体结合的抗原表位。最终成功筛选获得5株单克隆抗体,鉴定到3个与抗体结合的抗原表位,为下一步科学研究提供了初步且可靠的试验基础。

Abstract: The aim of this research was to prepare monoclonal antibodies against Mycoplasma capricolum subsp.capripneumoniae (M.capricolum subsp.capripneumoniae, Mccp), and also screen antibody binding epitopes. We inactivated Mccp with formaldehyde, and then immunized BALB/c mice. We applied conventional fusion cell technology to obtain hybridoma cell, subclones, and ascites of monoclonal antibodies. We used enzyme-linked immunoassay (ELISA) and immunoblotting (Western blotting) technologies to identify the specificity of monoclonal antibodies, and enzyme digestion method to identify antibody binding epitopes. Finally, we successfully screened five monoclonal antibodies and identified three antibody binding epitopes, which provided a preliminary and reliable experimental basis for further scientific research.

Key words: Mycoplasma capricolum subsp.capripneumoniae; monoclonal antibodies; antibody binding epitopes
