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.

Application

2′,7′-Dichlorofluorescin diacetate is suitable for use in:
  • sensitive and rapid quantitation of oxygen-reactive species in response to oxidative metabolism
  • 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.

Storage and Stability

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

CD133-positive cells in hepatocellular carcinoma (HCC) exhibit cancer stem cell (CSC)-like properties as well as resistance to chemotherapeutic agents and ionizing radiation; however, their function remains unknown. In this paper, we identified a hitherto unknown mechanism to overcome CD133-induced resistance

Oxidative stress is mediated, in part, by reactive oxygen species produced by multiple cellular processes and controlled by cellular antioxidant mechanisms such as enzymatic scavengers or antioxidant modulators. Free radicals, such as reactive oxygen species, cause cellular damage via cellular.
