Cell-permeable non-fluorescent reactive oxygen species (ROS) indicator. Passively diffuses across membranes where it is oxidized by peroxynitrite to rhodamine 123 which localizes in the mitochondria and exhibits green fluorescence (Ex/Em wavelengths of 500 and 536 nm). Used to investigate reactive oxygen intermediates produced by human and murine phagocytes, activated rat mast cells and cultured endothelial […]

5-DTAF is highly reactive with proteins. Unlike other reactive fluoresceins, 5-DTAF not only reacts with amino groups, but also reacts with thiol groups and even directly reacts with hydroxy groups such as polysaccharides and other alcohols in aqueous solution at pH above 9. Due to its high reactivity, 5-DTAF is also used to label carbohydrates. […]
