目的:制备鼠抗人B7-H4单克隆抗体(mAb),并对其生物学功能进行初步研究。方法以表达B7-H4分子的转基因细胞L929/B7-H4为免疫原,免疫Balb/c小鼠,采用杂交瘤技术,融合小鼠骨髓瘤细胞与脾脏细胞,用流式细胞术筛选阳性克隆,获得稳定分泌抗B7-H4 mAb的杂交瘤细胞株,并对mAb的生物学功能进行初步研究。结果成功获得1株稳定分泌抗人B7-H4 mAb的杂交瘤细胞株,命名为8F10。Western blot结果显示:8F10特异性识别B7-H4蛋白;T细胞增殖抑制阻断实验显示8F10可以阻断B7-H4对T细胞增殖的抑制作用。结论成功获得鼠抗人B7-H4 mAb,为进一步研究B7-H4分子的生物学功能提供了有效的工具。
