General description
2′,7′-ジクロロフルオレセインは、酸化感受性蛍光プローブです。2′7′-ジクロロフルオレセインジアセテートは、ROS（活性酸素種）の存在下で酸化されて2′7′-ジクロロフルオレセインを生じます。
Application
2′,7′-ジクロロフルオレセインは、細胞内のROS（活性酸素種）形成を測定するための酸化感受性蛍光プローブとして使用されています。[1]

In what types of applications can 2´,7´-Dichlorofluorescein be used?
1 回答-
Some applications for use of 2´,7´-Dichlorofluorescein are listed below. This product can be used for the determination of carbohydrates by fluorescence densitometry after TLC. See G. Gübitz et al., J. Chromatogr., 117, 337, (1976). 2´,7´-Dichlorofluorescein as also been used in the determination of H2O2 by chemiluminescence. See the following references by H. Watanabe et al. Anal. Sci. 2, 461, (1986) and T. Segawa et al. Anal. Sci. 6, 763, (1990). This product has also been used as a fluorescent additive used in indirect fluorimetric detection in OTC-HPLC. See W.D. Pfeffer and E.S. Yeung, J. Chromatogr., 506, 401, (1990).
