(3)单克隆抗体制备过程中的两次筛选第一次筛选:利用特定选择培养基筛选,获得能无限增殖的杂交瘤细胞;第二次筛选利用多孔板法和抗原一抗体杂交法筛选,获得产生特定抗体的杂交瘤细胞。故小鼠M的脾脏细胞与实验中骨髓瘤细胞进行融合,用选择培养基筛选得到具有无限增殖能力的细胞。将获得的上述细胞在多孔培养板上培养,用ICAM-1检测,从中选择能大量产生抗ICAM-1抗体的杂交瘤细胞,植入小鼠腹腔中克隆培养,一段时间后从小鼠腹水中提取所需用抗体。单克隆抗体的优点是特异性强、灵敏度高,可大量制备。(4)根据题干中实验目的“比较抗ICAN4一1单克隆抗体和.131]I对GD模型小鼠的治疗作用”可知,实验变量为注射的溶液种类,即抗体、131。,同时实验中需要注意单一变量原则和控制无关变量,所以单克隆抗体治疗组(C)中应给GD模型小鼠腹腔注射溶于0.1mL无菌生理盐水的抗ICAM-1单克隆抗体。
