一般說明
聚（2′-脱氧肌苷-2′-脱氧胞苷酸）钠盐是一种交替共聚物，其可作为DNA甲基转移酶的底物。
應用
聚(2′-脱氧肌苷-2′-脱氧胞苷酸) 钠盐已被用于转录因子AP-2 Alpha (TFAP2A)的电泳迁移率变动分析(EMSA)，以及人胚胎肾细胞(HEK293)核提取物的Southwestern印迹中。
适用于
- EMSA中的非特异性阻断剂
- DNA甲基转移酶的评估
- DNA-小分子或药物相互作用研究
生化／生理作用
聚(2′-脱氧肌苷-2′-脱氧胞苷酸)，聚(dI-dC)是一种合成的DNA底物。 在高盐下，聚(dI-dC)以左旋螺旋构象存在，并在减少盐浓度过程中恢复为右旋形式。 它在电泳迁移率变动分析(EMSA)中可用作非特异性竞争剂。
