Background:

Calcein Deep Red? AM is a fluorogenic probe. As the acetoxymethyl ester, Calcein Deep Red? AM is non-fluorescent but cell-permeant and is hydrolyzed to the fluorescent probe Calcein Deep Red? by intracellular esterases. Calcein Deep Red? is retained by live cells and displays excitation/emission maxima of 643/663 nm, respectively.
