Sourced in United States

DCFH-DA (2',7'-Dichlorodihydrofluorescein diacetate) is a fluorogenic compound used as an indicator for the detection of reactive oxygen species (ROS) in biological systems. It is a cell-permeable dye that can be oxidized by various ROS, including hydrogen peroxide, superoxide, and hydroxyl radicals, to produce the fluorescent compound 2',7'-dichlorofluorescein. The intensity of the fluorescent signal is proportional to the level of ROS present in the sample.

The generation of ROS in H358 cells was measured using a ROS sensitive fluorescent probe, 2,7-dichlorodihydrofluorescein diacetate (DCFH-DA, ThermoFisher). DCFH-DA can be oxidized to 2′,7′-dichlorofluorescein (DCF) by ROS and exhibits green fluorescence intensity.80 H358 cells were seeded on 25 × 25 mm microscope cover glass slips in BD Falon 60 × 60 mm tissue culture dishes for 72 h. Untreated cells were maintained as the negative controls whereas 10, 20 and 30% H2O2 solution in PBS was administered to cells for 15 minutes as positive controls.54 (link) H358 cells were also dosed with IC50 values of various complex as follows: 44+ (15 μM), 33+ (13 μM) and 22+ (1.7 μM) for 3 time periods of 2, 8, and 22 h. The cells were passaged and washed 3× in ice cold PBS then suspended in 10 mM DCFH-DA in PBS and incubated in the dark for 30 min. The levels of intracellular ROS were examined by confocal microscopy using long pass light filters and a 1.3 airy unit pinhole at 488/529 nm with a Zeiss axio-plane inverted fluorescence microscope.

To measure the intracellular ROS levels, MDA-MB-231 and MDA-MB-468 cells were pretreated with various concentrations of PP or 0.1% DMSO for 24 h and then incubated in the dark with 10 mM of the oxidation-sensitive fluorescent probe 2′7′-dichlorfluorescein-diacetate (DCFH-DA, Beyotime) for 20 min at 37°C. DCFH-DA was cleaved by intracellular esterase to liberate free DCFH, and the ROS level was measured using a BD Accuri C6 flow cytometer.

ROS Measurement using DCFH-DA Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
The intracellular ROS was measured using DCFH-DA (Sigma-Aldrich). This molecule diffuses through cell membranes and is hydrolyzed by intracellular esterase to liberate the free acid (2′, 7′ dichlorodihydrofluorescin (DCFH2)) which is trapped in the cells. DCFH2, upon reaction with oxidizing species, forms the highly fluorescent compound 2′, 7′- dichlorofluorescein (DCF). Thus, the fluorescence intensity was proportional to the amount of hydrogen peroxide produced by the cells. MDA-MB-231 cells were exposed to OEO/thymol for 12 h. After washing with PBS, the cells were incubated in DCFH-DA (20 μM) and kept in the dark for 15 min, and the intracellular fluorescence was measured using flow cytometry (FACSCalibur, BD Biosciences) with excitation and emission settings of 485–495 nm/525–530 nm, respectively81 (link),82 (link).

Cell apoptosis was detected in MC-3T3-E1 cell cultures using a flow cytometer. The cells were harvested and re-suspended in Annexin binding buffer at 1×105 cells/ml. Then, the suspension was incubated with Annexin V-FITC and propidium iodide (PI) [cat. no. 70-AP101-60; MultiSciences (Lianke) Biotech Co., Ltd., Hangzhou, China] in the dark for 15 min at 4°C. The apoptosis of the cell samples was analyzed by flow cytometry with BD CellQuest Pro Software version 1.2 (BD Biosciences, San Jose, CA, USA).
The ROS levels were measured using 2′,7′-dichlorodihydrofluorescein diacetate (DCFH-DA) as previously described (39 (link)). DCFH-DA (Sigma-Aldrich; Merck KGaA), without fluorescence, can enter the cell membrane and form DCFH in the cell. DCFH is then oxidized to form a fluorescent substance DCF in the presence of ROS. MC-3T3-E1 cells were stained with DCFDA and held for 30 min at room temperature. Finally, DCF fluorescence levels were measured by flow cytometry and the data were analyzed using Summit Software (version 4.3; Dako; Agilent Technologies, Inc., Santa Clara, CA, USA).
