The 2',7'-dichlorodihydrofluorescein diacetate (H2DCFDA), also known as dichlorofluorescin diacetate, is a cell-permeant indicator widely used to detect reactive oxygen species (ROS) in live cells. Its versatile applications include monitoring oxidative stress, detecting ROS intermediates, and studying cellular responses to environmental or physiological changes, such as ferroptosis.
Key Features
- ROS Detection:
- Sensitive detection of intracellular reactive oxygen species, including singlet oxygen, superoxide, hydroxyl radicals, and peroxides.
- Cell-Permeant Indicator:
- Easily enters cells, where intracellular esterases cleave acetate groups, and ROS oxidize the molecule to the fluorescent 2',7'-dichlorofluorescein (DCF).
- High Fluorescence Sensitivity:
- Detectable fluorescence with excitation/emission wavelengths of 492–495 nm/517–527 nm.
- Versatile Applications:
- Suitable for flow cytometry, fluorometry, fluorescence microscopy, and microplate reader analysis.
- Flexible Usage:
- Can be dissolved in DMSO, DMF, or ethanol for experimental applications.
- Enhanced Retention Versions:
- Modified variants (C400, C2938) with better cellular retention are available.
