Application
2′,7′-Dichlorofluorescein is used as fluorescent probe to measure ROS (Reactive Oxygen Species) for biological studies. It may also be used as a dip reagent for the fluorometric determination of vicinal diols, glycosides, and phenols.
General description
2′,7′-Dichlorofluorescein, also known as DCF is a fluorescent dye. The DCF fluorescence excitation is at 498nm with emission at 522nm. The lipophilic non-fluorescent Dcfh-DA readily crosses the cell membrane through passive diffusion followed by deacetylation. The deacylated product is an oxidant sensitive 2′,7′-dichlorofluorescein (DCHF). DCHF is oxidized later to form highly fluorescent DCF, which is measured.

Reactive oxygen species (ROS) are critically important chemical intermediates in biological studies, due to their multiple physiologically essential functions and their often pathologically deleterious effects. Consequently, it is vital that their presence in biological samples has to be quantifiable. However

Ca(2+) waves are initiated not only by Ca(2+) leak from the sarcoplasmic reticulum (SR), but also by Ca(2+) dissociation from the myofilaments in the myocardium with nonuniform contraction. We investigated whether contractile properties and the production of reactive oxygen species
