Abstract
以仿生多肽配基FYEILHC为亲和配基、以葡聚糖修饰的聚甲基丙烯酸缩水甘油酯Dextran-poly(glycidyl methacrylate),Dextran-PGMA超大孔微球为基质,制备用于单克隆抗体纯化的仿生多肽超大孔PGMA微球,在环氧氯丙烷中滴加2 mol/LNaOH使其表面衍生出环氧基,在表面修饰FYEILHC;用扫描电镜表征微球表面形貌,用AKTA蛋白纯化系统考察了Dextran-PGMA微球和琼脂糖微球对抗体的动态吸附量随线性流速的变化。结果表明,偶联FYEILHC后Dextran-PGMA微球仍能保持其大孔结构,在923cm/h线性流速下,其对抗体的动态吸附量仅下降约8%,而琼脂糖微球的动态吸附量则迅速下降25%。表明在较高流速下,抗体在Dextran-PGMA微球上的传质性能较好。吸附-用0.1mol/LNa OH原位清洗重复40次后,Dextran-PGMA微球对抗体的动态吸附量约为(21±1)mg/mL,表明微球具有良好的化学稳定性;血清中回收的抗体纯度为95.0%,表明仿生多肽亲和介质具有从复杂生物样品中纯化抗体的巨大潜力,可满足高流速、高通量抗体分离纯化需求
