Briefly, K562 cells were seeded in 6-well plates and treated with certain concentrations of Mere15 (0–80 μg/mL) for 24 h. Then cells were incubated in serum-free culture medium with DCFH-DA … WebApr 1, 2007 · Extracellular H 2 O 2 production can also be measured using horseradish peroxidase catalyzed oxidation of compounds that increase or decrease in fluorescence . ... (DCFH) oxidation, which is at best an approximation and frequently erroneous because reactions that are not dependent upon H 2 O 2 can also result in DCFH oxidation [9, 10].
WebDichloro-dihydro-fluorescein diacetate (DCFH-DA) assay: a quantitative method for oxidative stress assessment of nanoparticle-treated cells. No consensus exists on how … WebReactive oxygen species (ROS) such as superoxide anion, hydrogen peroxide, and hydroxyl radicals are believed to be initiators of peroxidative cell damage. This paper focused on the use of 2',7'-dichlorofluorescein-diacetate (DCFH-DA) to quantitate cerebral ROS as an index for neurotoxicity.

WebJan 10, 2003 · Dichlorodihydrofluorescein (DCFH) is one of the most frequently used probes for detecting intracellular oxidative stress. In this study, we report that H2O2-dependent intracellular oxidation of DCFH to a green fluorescent product, 2',7'-dichlorofluorescein (DCF), required the uptake of extracellular iron transported through a transferrin receptor … is sand rockWebJan 1, 2009 · DCFH 2 can be directly oxidized to DCF by peroxynitrite. Inhibitors of NOS should be used to prevent NO mediated DCFH 2 oxidation . Some cell types have low esterase activity. This can have important implications for detecting ROS because DCFH-DA needs to be hydrolysed to DCFH 2 by cellular esterases. Careful consideration must be … identity tm dauerWebDichlorofluorescin (DCFH) is a probe that is trapped within cells and is easily oxidized to fluorescent dichlorofluorescein (DCF).
