ROS水平一旦超过内源性抗氧化防御的能力,氧化还原平衡被破坏,就会导致DNA、脂质、蛋白质的结构或构像改变,最终导致细胞死亡。
ROS水平是细胞正常生理功能和环境因素导致细胞损伤的重要信号,检测细胞内ROS水平对于理解一些药物作用的信号通路和潜在作用机制具有重要意义。因此选择合适的探针检测ROS对于疾病机理研究以及药物筛选具有重要作用。

首先,确保有一个阳性(ROS诱导)和一个阴性(未处理)样本进行对照。甲萘醌(100 µM, 1 h)或是奈法唑酮(50 µM, 24 h)可作为阳性对照。H2O2虽然不能很好地与CellROX染料兼容,但也可以用于阳性对照。
尝试着增加染料浓度和标记时间。
尽快完成活细胞成像实验。
确保使用的滤光片和仪器设置与染料的激发和发射光谱相匹配。
某些情况不能存在血清。如H2DCFDA染料需要酯酶切割,血清中包含的酯酶会提前切割染料。
