Description
Recommended products
2-Methyl-13-Cyclopentanedione 97.0%(GC)
Application
27-Dichlorofluorescein diacetate may be used as a superior gas phase alternative to underivatized fluorescein and as a componentsubstrate of the 27-dichlorofluorescein diacetate assay to quantitate reactive oxygen species (ROS). It may also be used as a dip reagent for the fluorimetric determination of vicinal diols glycosides and phenols.
Purpose
For R&D use onlynot for drug household or other uses.
General Description
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. It is also used in the cellular antioxidant activity (CAA) assay. Dichlorofluorescin is a probe that is trapped within cells and is easily oxidized to fluorescent dichlorofluorescein. The method measures the ability of compounds to prevent the formation of DCF by 22-Azobis(2-amidinopropane) dihydrochloride (ABAP)-generated peroxyl radicals in human hepatocarcinoma HepG2 cells.
