- Description
- CFDA is a popular, sensitive, 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. The cleavage product produced upon enzymatic or chemical hydrolysis of the acetate group(s) is carboxyfluorescein which is well-retained inside live cells, while the substrate CFDA is membrane permeant.
