2′,7′-Dichlorofluorescin diacetate is a cell-permeable non-fluorescent probe. 2′,7′-Dichlorofluorescin diacetate is de-esterified intracellularly and turns to highly fluorescent 2′,7′-dichlorofluorescein upon oxidation.
D 9474 (OTTO) 2′,7′-Dichlorofluorescin diacetate, ≥97% Cas 4091-99-0 - used sensitive and rapid quantitation of oxygen-reactive species in response to oxidative metabolism; microplate assay for detecting oxidative products in phagocytic cells, and quantitative multiwell myeloid differentiation assay.
