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 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

Uses

Determn of intracellular Zn2+ and labile Zn2+ ions.
