• Product overview

  DCFDA - Cellular ROS Assay Kit / Reactive Oxygen Species Assay Kit (ab113851) uses the cell permeant reagent 2’,7’ –dichlorofluorescin diacetate (DCFDA, also known asH2DCFDA, DCFH-DA, and DCFH)to quantitatively assess reactive oxygen species in live cell samples.

  
  

  DCFDA / H2DCFDA / DCFH-DA / DCFH is a fluorogenic dye that measures hydroxyl, peroxyl and other reactive oxygen species (ROS) activity within the cell.NB: DCFDA and DCFA are also available as free molecules as ab145286 (Carboxy-DCFDA N-succinimidyl ester) and ab145439 (5(6)-Carboxy-2',7'-dichlorofluorescein).

  
  

  The DCFDA assay protocol is based on the diffusion of DCFDA / H2DCFDA / DCFH-DA/ DCFH into the cell. It is then deacetylated by cellular esterases to a non-fluorescent compound, which is later oxidized by ROS into 2’, 7’ –dichlorofluorescein (DCF). DCF is highly fluorescent and is detected by fluorescence spectroscopy with excitation / emission at485 nm / 535 nm.

• Notes

  Previously calledDCFDA / 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. The number of measurements in microscopy is dependent on experimental setup.

  This kit is not compatible with fixed samples. Stained cells must be measured live.

  For reactive oxygen species, the most popular live cell ROS assay is DCFDA Assay ab113851 (green). Alternative ROS assays are available in orange (ab186028), red (ab186027), and deep red (ab186029). ab238535 is used to measure ROS in biofluids, culture supernatants and cell lysates.

  For assays designed to differentiate ROS, superoxides, and reactive nitrogen species: to assay ROS and superoxides use ab139476; to assay ROS, superoxides, and reactive nitrogen species use ab139473; to assay superoxides use ab219943.

  Effect of anethole on excessive ROS generation in hMSCs.hMSCs were exposed at 2mM H₂O₂for 30min and incubated for 2days in presence or absence of 50μM anethole. ROS was measured by staining the cells with DCFDA cellular ROS detection assay kit according to the manufacturer’s instructions.ROS generation was observed under a fluorescence microscope at 200× magnification.

• DCFDA ROS assay used to study Doxorubicin cardiotoxicityKobashigawa et al. (Pubmed 28056084)

  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.

  ROS levels analysis in human immortalized cardiomyocytes cells withab113851 under different treatment conditions.

  Data are mean ± SEM of three different experiments. H2O2 800μM was used as Positive Control. The values of fluorescence intensity at each time point are indicated as the ratio of the value at specific t-time point on the value at time point zero (first measurement) (t-time point/t0). Briefly, cells were plated (seeding density 2.5 x 104 cells/cm2) in FBS-supplemented medium w/o phenol red onto a 96 black well plate. After 24 hours the cells were washed one time with 1X buffer (provided in the kit), then the cells were incubated with DFCDA 10 μM for 30 min at 37° C protected from light. Following incubation the wells were washed with PBS and the cells were exposed to treatments of interest in FBS-supplemented medium w/o phenol red. ROS production was determined immediately by measuring the formation of fluorescent dichloro fluorescein (DCF), using a PerkinElmer VICTOR3, at an Ex-485 and Em-535 nm. Measurements were done every 30 min for six hours. The value of fluorescence intensity at each time point is reported. The value reported was obtained by the ratio of fluorescence at specific time point on fluorescence at time 0, which was measured immediately after DCFDA incubation.
