DCFDA - Cellular ROS Assay Kit / Reactive Oxygen Species Assay Kit (ab113851) uses the cell permeant reagent 2’,7’ –dichlorofluorescin diacetate (DCFDA, also known as H2DCFDA), a fluorogenic dye that measures hydroxyl, peroxyl and other reactive oxygen species (ROS) activity within the cell.
After diffusion in to the cell, DCFDA / H2DCFDA is deacetylated by cellular esterases to a non-fluorescent compound, which is later oxidized by ROS into 2’, 7’ –dichlorofluorescein (DCF). DCF is a highly fluorescent compound which can be detected by fluorescence spectroscopy with excitation / emission at 495 nm / 529 nm.
DCFDA assay protocol / ROS assay protocol summary (microplate):
- collect suspension cells in tube / seed and allow attachment of adherent cells in 96-well plate
- wash in buffer
- stain with DCFDA for 30 min (suspension) / 45 min (adherent), wash with buffer
- if suspension cells, transfer to microplate
- analyze with microplate reader
DCFDA assay protocol / ROS assay protocol summary (flow cytometry):
- collect cells in tubes
- stain with DCFDA for 30 min (without washing)
- analyze with flow cytometer
Previously called DCFDA / H2DCFDA - Cellular Reactive Oxygen Species Detection Assay Kit.
This kit contains sufficient materials for approximately 300 measurements in microplate format and 70 measurements (35 mL) by flow cytometry.
This kit is not compatible with fixed samples. Stained cells must be measured live.

Kobashigawa et al. (Pubmed 25127116) used the DCFDA ROS assay ab113851 to investigate the causes of the protective effects of metformin (Met) treatment in Doxorubicin (Dox) induced cardiotoxicity.
They identified that in metformin treated H9c2 rat immortalized cardiomyoblasts, Met treatment reduced ROS levels induced by Dox (A). Values represent mean ± S.D. (n = 4).
In combination with other assays, they developed the hypothesis that Dox induces increased ROS expression, leading to increased calcium levels and cell death, and that Met reduces this effect by increasing AMPK expression.
ab113851 (DCFDA) labeled and unlabeled Jurkat cells were treated with 50 µM tert-butyl Hydrogen Peroxide (tbHP), then analyzed by flow cytometry.
Jurkat cells were labeled with DCFDA (20 µM) or unlabeled (none) and then cultured an additional 3 hours with or without 50 µM tert-butyl hydrogen peroxide (TBHP) according to the protocol. Cells were then analyzed on a fluorescent plate reader. Mean +/- standard deviation is plotted for 4 replicates from each condition. TBHP mimics ROS activity to oxidize DCFDA to fluorescent DCF.
Labeled HL60 cells were treated with idarubicin or doxorubicin for 4 hours at multiple doses according to the protocol. At the end of the treatment cells were read end point in a fluorescent plate reader (Perking Elmer-Wallac 1420 Victor 2 Multilabel plate reader). Mean +/- standard deviation is plotted for 3 replicates from each condition. The dotted line represents the mean of 24 replicates of HL60 cells treated with 0.5% DMSO.
