Membrane-permeant, ratiometric Ca²⁺ indicator.

Excitation:	_340/380 nm_
Emission:	--505 nm______
Kd:	_145 nM______

Membrane-impermeant, ratiometric Ca²⁺ indicator.

Excitation:	_340/380 nm_
Emission:	--505 nm______
Kd:	_145 nM______

Membrane-permeant, non-fluorescent Ca²⁺ chelator.

Calcein AM is a membrane-permeant, non-fluorescent form of calcein that enters cells passively. Once inside the cytosol of cells, Calcein AM is converted to green-fluorescent Calcein by ubiquitous esterases in viable cells, resulting in uniform cytosolic fluorescence (Ex/Em 495 nm/515 nm)
