Dichlorofluorescein (DCF) is an organic dye of the fluorescein family, being substituted at the 2 and 7 positions by chloride. It is used as an indicator for argentometry by Fajans method. When used as an indicator, upon reaching the equivalence point of a titration reaction the color shifts from colorless towards a faint pink.

  • Dichlorofluorescein (DCF) is an organic dye of the fluorescein family, being substituted at the 2 and 7 positions by chloride. It is used as an indicator for argentometry by Fajans method. When used as an indicator, upon reaching the equivalence point of a titration reaction the color shifts from colorless towards a faint pink. It is also used in the (CAA) assay. Dichlorofluorescin (DCFH) is a probe that is trapped within cells and is easily oxidized to fluorescent dichlorofluorescein (DCF). The method measures the ability of compounds to prevent the formation of DCF by 2,2'-Azobis(2-amidinopropane) dihydrochloride (ABAP)-generated peroxyl radicals in human hepatocarcinoma HepG2 cells. By itself, dichlorofluorescin (DCFH) also quantifies intracellular hydrogen peroxide as well as cellular oxidative stress. (en)
  • La diclorofluoresceina (DCF) è un indicatore e un pigmento della famiglia delle fluoresceine, utilizzato nelle titolazioni precipitometriche e argentometriche dal metodo di Fajans, con due atomi di cloro come sostituenti nelle posizioni 2 e 7. Viene anche utilizzata nei test per misurare l'attività antiossidante cellulare (CAA, dall'inglese "cellular antioxidant activity"). La diclorofluoresceina viene infatti usato come una sonda e inserito nella cellula, dove può essere facilmente ossidato a dare un composto fluorescente. Il metodo misura quindi l'abilità di una molecola nel prevenire la formazione di questo composto. (it)
