Application

Zinquin has been used to detect intracellular zinc.

Biochem/physiol Actions

Zinquin is a membrane-permeant fluorophore. It is used to detect zinc in cells by UV fluorescence. Zinquin ethyl ester can be used to monitor the change in intracellular concentrations of Zn2+ in thymocytes and hepatocytes. The ester is excited at 368nm and emits at 490nm.

Zinc signals, i.e. a change of the intracellular concentration of free zinc ions in response to receptor stimulation, are involved in signal transduction in several immune cells. Here, the role of zinc signals in T-cell activation by IL-2 was investigated
