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 zinc ion with two nitrogen atoms in the structure. Used for studying the role of zinc in apoptosis. Fluorescence: max. Abs. l = 368nm, max. Em. l = 490nm
