What is ZINQUIN ETHYL ESTER?
Chemical properties
White or Pale Blue Crystalline Solid
The Uses of ZINQUIN ETHYL ESTER
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
The Uses of ZINQUIN ETHYL ESTER
Zinquin ethyl ester is a lipophilic, zinc-sensitive, cell-permeable fluorescnet probe.
What are the applications of Application
Zinquin, Free Acid is a Zn2+ specific fluorophore that forms zinquin-Zn2+ complexes
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.
