Hydrogen peroxide (H₂O₂) is involved in therapeutic processes such as wound healing, anti-bacterial defense, stem cell proliferation, and an adaptive response in astrocytes that leads to neuronal protection. However, over-production of H₂O₂ exerts toxic effects on the cell and its surrounding environment. Over-production of H₂O₂ is connected to serious pathological conditions such as cancer, ageing, diabetes, and neurodegenerative diseases.BioTracker Green free H₂O2 dye is a fluorescent probe that fluoresces upon reaction with H₂O₂ , but does not react with other ROS such as hydroxyradical (-OH), superoxide (O2-), hypochlorous acid (HOCl), singlet oxygen (¹O₂), and nitric oxide (NO). This dye cannot penetrate cell membrane but can be used for detection of extracellular H₂O₂ and in free solutions.
