Verwenden
2',7'-Dichlorofluorescein is used as an indicator and as a cellular antioxidant activity. It is also used for the determination of carbohydrates and hydrogen peroxide by fluorescence densitometry and chemiluminescence respectively. It is used as an indicator for argentometry by Fajans method. It is also involved in the cellular antioxidant activity assay. It is utilized as an additive in fluorescence and laser studies.
Definition
2',7'-dichlorofluorescein is a member of 2-benzofurans. It has a role as a fluorochrome. It derives from a fluorescin.
Application
2',7'-dichlorofluorescein has been used as an oxidation-sensitive fluorescent probe to measure ROS (reactive oxygen species) formation in cells.
Biologische Aktivität
2',7'-dichlorofluorescein is an oxidation-sensitive fluorescent probe. 2′7′-dichlorofluorescein diacetate is oxidized to 2′7′-dichlorofluorescein in the presence of ROS (reactive oxygen species).
