摘要: 背景与目的: 制备绿色荧光蛋白(GFP)的小鼠多克隆抗体。材料与方法: 以GFP转基因小鼠肌肉为抗原,与免疫佐剂混匀后免疫同品系小鼠, 4周后取血,以收集的血清做免疫细胞化学和免疫组织化学,Western blot分析。 结果: 收获的抗体在1∶200稀释度时能显示强阳性结果。 结论: 直接用GFP转基因小鼠肌肉为抗原可在较短时间内大量制备GFP多克隆抗体,并能对转染有GFP阳性细胞的肝组织取得良好的检测效果。

Abstract: BACKGROUND & AIM: To prepare green fluorescent protein(GFP) polyclonal antibody. MATERIALS AND METHODS: Muscle from one GFP-transgenic mouse was taken as antigen, mixed with adjuvant sufficiently,then immunized homogeneous mice. Blood was collected 4 weeks later and the serum was used for immunocytochemistry, immunohistochemistry and western blot. RESULTS: The serum we collected showed strong positive response when diluted at 1∶200. CONCLUSION: Green fluorescent protein polyclonal antibody could be prepared directly with muscle of GFP-transgenic mouse, with which we efficiently detected GFP positive cells transplanted in the liver.

Key words: green fluorescent protein, polyclonal antibody, transgenic mouse
