Used to differentiate viable cells from apoptotic cells. Live cells that are not apoptotic accumulate 6-carboxyfluorescein but do not accumulate annexin. CFDA enter cells and are hydrolysed more slowly than FDA. CFDA and FDA hydrolyses obey Michaelis-Menten kinetics with Km values of around 19 and 2 microM, respectively.
