一般說明
2′,7′-二氯二氢荧光素二乙酸酯（DCFH-DA）是一种对氧化敏感的荧光染料，用于检测细胞内活性氧（ROS）水平。DCFH-DA是一种细胞渗透性非荧光探针，可被细胞内酯酶水解为DCFH，当被细胞内的ROS氧化时形成荧光DCF。
The excitation wavelength is 504 nm and emission wavelength is 529 nm in ethanol. The use of DMSO as the solvent has not been determined, however various publications suggest that it is suitable.
應用
2′,7′-二氯荧光素二乙酸酯适用于：
- 敏感并快速定量活性氧，以响应氧化代谢
- 微孔板法，以检测吞噬细胞中的氧化产物
- 定量多孔髓样分化测定
适用于：敏感并快速定量活性氧，以响应氧化代谢；微孔板法，以检测吞噬细胞中的氧化产物；髓样分化定量多孔测定。

氧化应激，在一部分上，是由多种细胞过程产生的活性氧介导，并由诸如酶清除剂或抗氧化剂调节剂等细胞抗氧化剂机制所控制的。自由基，如活性氧，会通过细胞引起细胞损伤。
Cellular oxidative stress is countered by enzymatic scavengers and antioxidant modulators against reactive oxygen species damage.
