Popular, ultrasensitive, fluorescent substrate for measuring esterase activity in live cells often used in cell viability assays and "Live-Dead" assay systems, especially in flow cytometry.

  • Useful in cell viability assays
  • Esterase substrate

This reagent is useful for automated cell viability assays because the cleavage product produced upon enzymatic or chemical hydrolysis of the acetate group(s) is carboxyfluorescein. This fluorophore is well-retained inside live cells, while the substrate CFDA is membrane permeant.
