Description

General description

5(6)-Carboxy-2′,7′-dichlorofluorescein diacetate or CDFDA is a fluorescent oxidant sensing probe. 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.

Application

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

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Analysis Note

Exc_max: 504 nm (Lit.)

Other Notes

Intracellular esterase substrate with low sensitivity of fluorescence to intracellar pH
