CytoTrace Red™ CFDA is a fluorescein-based dye used as a long-term cell tracer. It is nonfluorescent but cell-permeant and, upon entering the cell, is converted to a fluorescent compound by intracellular esterases.1 CytoTrace Red™ CFDA is retained by living cells and displays excitation/emission spectra of 560/574 nm, respectively. It remains fluorescent for at least 24 hours and is retained through cell division for several cycles. The fluorescence survives fixation, allowing for immunocytochemistry techniques to be applied as well.WARNING This product is not for human or veterinary use.
