Description

Calcein Blue, AM is a cell-permeant esterase substrate that can serve as a viability probe that measures both enzymatic activity and cell-membrane integrity, which is required for intracellular retention of their fluorescent product. Calcein blue AM is only weakly fluorescent (excitation/emission maxima ~322/435 nm). Upon cleavage of the AM esters by intracellular esterases, this tracer becomes relatively polar and is retained by cells for several hours. In addition, its fluorescence intensity increases and its fluorescence spectra shift to longer wavelengths, with excitation/emission maxima of ~360/449 nm.
For Research Use Only. Not for use in diagnostic procedures.
