General description

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.[1]
The excitation wavelength is 504 nm and emission wavelength is 529 nm in ethanol. The use of DMSO as the solvent has not been determined, however various publications suggest that it is suitable.

Application

2′,7′-Dichlorofluorescin diacetate is suitable for use in:
  • sensitive and rapid quantitation of oxygen-reactive species in response to oxidative metabolism[2][1][3]
  • microplate assay for detecting oxidative products in phagocytic cells
  • quantitative multiwell myeloid differentiation assay

Applications include sensitive and rapid quantitation of oxygen-reactive species in response to oxidative metabolism; microplate assay for detecting oxidative products in phagocytic cells, and quantitative multiwell myeloid differentiation assay.

Preparation Note

This product should be stored in powdered format at -20°C.

Questions

1–10 sur 14 questions  

  1. Can you suggest a protocol for detection of ROS in colon tissue from rat?

    1 réponse

    1. This product is not tested specifically for in vitro or in vivo use. A protocol is not currently available. However, a search of the literature reveals several publications that may be helpful. Please see the links below to review examples:

      A method to determine reactive oxygen species production in intestinal and liver cell cultures using the 2’,7’-dichlorodihydrofluorescein diacetate assay
      https://www.sciencedirect.com/science/article/pii/S2215016124000694

      Utile ?

  2. Is the product compatible with RFP transfected cells?

    1 réponse

    1. Yes, RFP (Red Fluorescent Protein) and DCFH (2′,7′-Dichlorodihydrofluorescein) are spectrally compatible and can be used together for multicolor imaging or flow cytometry.

      Utile ?

  3. Hi, is the product suitable for ROS detection in a cell-free system? If not, could you please recommend a DCFH related product that works in a system without cells? Thanks

    1 réponse

    1. This product as supplied is DCFH-DA and used for intracellular ROS detection. Please see the link below for understanding this process.
      https://pubs.acs.org/doi/10.1021/acs.analchem.7b00043

      For use in a cell-free system, deacetylation of DCFH-DA into DCFH must be performed before use.
      Please see the link below for this method.
