摘要 目的:制备能特异识别结合人APPβ水解位点的单克隆抗体(mAb)。方法:以APPβ水解位点短序列多抗原肽免疫BALB/c小鼠,取脾细胞和骨髓瘤细胞Sp2/0进行常规融合,通过间接ELISA和有限稀释法进行筛选和亚克隆,获得能分泌针对APPβ水解位点mAb的杂交瘤,采用ELISA、Western blot等方法对其特异性进行检测。结果:获得2株稳定分泌抗人APPβ水解位点mAb的杂交瘤细胞株,分别命名为1A7和2H10,其Ig亚类分别为IgGl和lgG2b。Western blot显示2株抗体可以与全长APP结合。结论:成功制备了能特异识别结合APPβ水解位点的mAb,为进一步研究其对β位点封闭功能和构建小分子抗体奠定基础。
