2′,7′-Dichlorofluorescein diacetate, also known as DCFHDA or Dcfh-DA, is a sensitive cell-permeable redox probe. The lipophilic non-fluorescent Dcfh-DA readily crosses the cell membrane through passive diffusion followed by deacetylation.

The cell-permeant 2',7'-dichlorodihydrofluorescein diacetate (H 2 DCFDA) (also known as dichlorofluores cin diacetate) is a chemically reduced form of fluorescein used as an indicator for reactive oxygen species (ROS) in cells, for example to detect the generation of reactive oxygen intermediates in neutrophils and macrophages.

No consensus exists on how to address possible toxicity of nanomaterials as they interfere with most in vitro screening tests based on colorimetric and fluorimetric probes such as the dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay for detection of oxidative species. In …

Cell permeant reagent 2’-7’dichlorofluorescin diacetate (DCFH-DA) is a fluorogenic dye that measures hydroxyl, peroxyl and other ROS activity. After cell uptake, DCFH-DA is deacetylated by cellular esterases to a non-fluorescent compound, which is later oxidized by ROS into 2’-7&rs

2017年2月22日 · DCFH 2 -DA (2′,7′-dichlorodihydrofluorescein diacetate) is the most widely used fluorogenic probe for the detection of general oxidative stress. However, the use of DCFH 2 -DA, as many other fluorogenic redox probes, is mainly confined to the detection of intracellular oxidative stress in vitro.

DCFH-DA staining is a simple and cost-effective way to detect ROS in cells. It can be used to measure ROS generation after chemical treatment or genetic modifications. Therefore, it is useful for determining cellular oxidative stress upon environment stress, providing clues to …

The assay works by utilizing the fluorescent probe 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) to detect the presence of ROS. DCFH-DA is taken up by cells and is converted to dichlorofluorescein (DCFH) by intracellular esterase. DCFH is oxidized by ROS to the strong fluorescent DCF.

2′,7′-Dichlorodihydrofluorescein diacetate (DCFH-DA) is an oxidation-sensitive fluorescent dye used to detect the intracellular reactive oxygen species (ROS) level. DCFH-DA is a cell-permeable non-fluorescent probe, that can be hydrolyzed by intracellular esterase to DCFH, which forms fluorescent DCF when oxidized by the intracellular ROS.

DCFH-DA (5 μM; 30 min). DCFH‐DA, a specific indicator for ROS detection, is employed to evaluate overall ROS levels in 4T1 cells. H2DCFDA purchased from MCE. Usage Cited in: ACS Nano. 2025 Jan 25. Inside A375 melanoma cells, the ROS level is measured with the help of the DCFH-DA probe under CLSM imaging.

2021年7月15日 · Dichlorodihydrofluorescein diacetate (DCFH-DA) has been widely used in detection of reactive oxygen species (ROS). Unfortunately, the detection process is easily affected by light irradiation during measurement, which cannot be overlooked especially for samples with a small amount of ROS.
