摘要
目的 :制备抗大鼠牙本质基质蛋白 1(dentinmatrixprotein 1,DMP1)的单克隆抗体 ,研究其在牙胚发育过程中的时空表达。方法 :以重组的DMP1为抗原 ,免疫Balb/c小鼠 ,通过细胞融合 ,建立分泌单克隆抗体的杂交瘤细胞系。用免疫组化方法检测DMP1在牙胚发育过程中的表达。结果 :获得了 2株稳定分泌抗DMP1特异性抗体的杂交瘤细胞 ,两株单克隆抗体的亚类均为IgG1,与重组的DMP1蛋白和牙齿组织总蛋白均可特异性反应。DMP1在磨牙和切牙分泌性成牙本质细胞胞浆顶端及切牙成釉细胞中有表达。结论 :通过杂交瘤技术 ,获得了 2株抗DMP1的单克隆抗体。DMP1在大鼠磨牙发育过程中的分布具有时空特异性 ,可能促进牙本质矿化 ,诱导前成釉细胞向成釉细胞分化
