5(6)-CDCFDA (ultra pure)

5(6)-CDCFDA is an amine–reactive fluorescein diacetate (FDA) derivative used to prepare a variety of FDA conjugates. 5(6)-CDCFDA is a non-fluorescent molecule that diffuse into cells and is hydrolyzed by intracellular non-specific esterases, yielding a fluorescent probe. The probe accumulates exclusively in cells with intact cell membranes. 5(6)-CFCFDA does not stain dead cells. 5(6)-CDCFDA labeling can be used for monitoring cells by flow cytometry or fluorescence microscopy. The probe is also frequently used to monitor reactive oxygen species (ROS) generation in live cells. Wavelength Maxima: Excitation 504nm, Emission 529nm
