Sigma Aldrich Fine Chemicals Biosciences BioTracker Green H2O2 Live

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 H2O2 live cell 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 is cell permeable and initially has low reactivity with H2O2 but it is quickly hydrolyzed by intracellular esterases to generate a reactive and cell impermeable product that fluoresces upon reaction with H2O2.
