ZINQUIN ETHYL ESTER Usage And Synthesis

Chemical Properties

White or Pale Blue Crystalline Solid

Uses

A fluorescent reagent and indicator of intracellular zinc ions. An analogue of widely used indicator, TS-Q. Zinquin ethyl ester is membrane permeable therefore useful to detect intracellular zinc ions. Zinquin ethyl ester forms a complex with a zin

Uses

Zinquin ethyl ester is a lipophilic, zinc-sensitive, cell-permeable fluorescnet probe.

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.
