TSQ is one of the most efficient membrane-permeable fluorescent probes for zinc (II). It is selective for Zn (II) in the presence of physiological concentrations of Ca (II) and Mg (II) ions. Fluorescence of Zinquin ethyl ester is enhanced upon binding Zn (II), but the probe does not demonstrate a shift or change in emission wavelength. TSQ forms a largely insoluble 2:1 (Ligand-Metal) complex with zinc and emits blue light upon excitation at 365 nanometers. TSQ has been extensively applied to study Zn (II) in mossy fibers of the hippocampus. TSQ has been used to monitor intracellular zinc fluxes associated with apoptosis as well. Wavelength Maxima: Excitation 344nm, Emission 385nm
