Fura Red AM, a fluorescent probe, is utilized for visualizing cytosolic [Ca(2+)] distribution in living plant tissue under an excitation wavelength of 488 nm [1].

Fura Red AM is exclusively used for undifferentiated cells, as differentiating cells exhibit significant autofluorescence in the Fura Red channel. The stock solution of Fura Red AM is recommended to be prepared in dimethyl sulfoxide (DMSO) at a concentration of 45.91 mM [1].
