Carboxyfluorescein is a fluorescent dye with an excitation and emission of 492/517 nm, respectively. It is commonly used as a tracer agent. The dye is membrane-impermeant and can be loaded into cells by microinjection or scrape loading.^[1] It can be incoporated into liposomes, and allow for the tracking of liposomes as they pass through the body. In addition, Carboxyfluorescein has been used to track division of cells.^[2]
