· 多克隆抗体多克隆抗体是动物体内生成多种不同抗体B细胞的活化结果。它们被视为抗体混合物,可与抗原表面的多个表位反应多克隆抗体抗原识别灵活性更高,亲和力更强,兼容更广泛的应用。但是同时也可能产生非特异性结合带来的高背景和批次间的不稳定性。
· 单克隆抗体单克隆抗体通过杂交瘤技术生产,每个B细胞产生针对特定抗原表位的特异性抗体,同一克隆的抗体产生完全相同的抗体拷贝。因此单克隆抗体具有高特异性、批间一致性和重复性等特点。然而单克隆抗体可能会出现识别抗原丢失或隐蔽,实验应用受限等问题,杂交瘤细胞系漂变也会影响单抗的表达。
制备单克隆抗体的一般步骤:
1 免疫动物选择:
根据需要产生目标抗原的免疫反应,选择合适的免疫动物。例如,小鼠是最常用的免疫动物之一,因其易于操作且在免疫应答方面较为强大。
2 抗原免疫
将目标抗原注射到免疫动物体内,通常需要多次免疫以激发免疫反应。可以选择不同的免疫路线,如皮下、腹腔、静脉等。
3 细胞融合
从免疫动物获得脾细胞或淋巴细胞,与骨髓瘤细胞或其他癌细胞(如SP2/0、NS0等)融合,形成杂交瘤细胞。融合细胞通常使用聚乙烯醇(PEG)或电穿孔等方法促进细胞融合。
4 杂交瘤细胞筛选
对融合细胞进行筛选,一般使用HAT选择性培养基,通过对非杂交瘤细胞和单克隆杂交瘤细胞的抗代选择,筛选出产生目标抗体的单克隆杂交瘤细胞。
5 单克隆抗体生产
从筛选出的单克隆杂交瘤细胞中获取单一细胞系,并进行大规模培养和产生抗体。一般可采用体外或体内方式生产单克隆抗体。
6 抗体纯化
通过不同的方法对产生的单克隆抗体进行纯化,去除杂质,例如使用蛋白A/G层析、蛋白L层析、蛋白G层析等。
7 鉴定和验证
对纯化后的单克隆抗体进行鉴定和验证,例如使用酶联免疫吸附实验(ELISA)、免疫印迹(Western blotting)等方法,确定其免疫特异性和活性。
8 应用
将制备好的单克隆抗体应用于具体的研究、诊断或治疗等领域,例如免疫组化、流式细胞术、免疫疫治疗等。
