Allgemeine Beschreibung

5(6)-Carboxy-2′,7′-dichlorofluorescein diacetate or CDFDA is a fluorescent oxidant sensing probe.[1] It is an intracellular probe added to the cells as a pro-substrate, which upon hydrolysis by the esterase enzyme produces the fluorescent product called CDF.[2]

Anwendung

5(6)-Carboxy-2′,7′-dichlorofluorescein diacetate or Carboxy-DCFDA is used as a cell permeate probe to detect intracellular reactive oxygen species (ROS). [3] The anionic fluorescent dye, 5(6)-Carboxy-2′,7′-dichlorofluorescein diacetate is suitable for studying Multi-Drug Resistance (MDR) by target cells.[4]
