Description:
CFDA is a popular, ultrasensitive, fluorescent substrate for measuring esterase activity in live cells. It is often used in cell viability assays and "Live-Dead" assay systems, especially automated cell viability assays, because the cleavage product produced upon enzymatic or chemical hydrolysis of the acetate group(s) is carboxyfluorescein Product M0122. This fluorophore is well-retained inside live cells, while the substrate CFDA is membrane permeant. See the references for additional information about CFDA use in bacterial, plant, yeast and mammalian cell culture.

Application:
Cell labeling reagent with green emission spectral properties (Abs 488 nm / EM 517 nm) after removal of acetate esters, intracellularly.
