CFDA (Ultra Pure)
from
Enzo Life Sciences, Inc.
Description
CFDA is an amine-reactive fluorescein diacetate (FDA) derivative used to prepare a variety of FDA conjugates. FDA and its derivatives are non-fluorescent molecules that diffuse into cells and are hydrolyzed by intracellular nonspecific esterases, yielding fluorescent probes. These probes accumulate exclusively in cells with intact cell membranes. CFDA does not stain dead cells. FDA 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 494nm, Emission 521nm
