Product Information
Description: MQAE is a novel chloride ion fluorescence probe excited by ultraviolet light. MQAE, binding bromine ion as ligand, can be used to detect the activity of chloride. MQAE exhibits a reduction of fluorescence intensity with the increase of intracellular Cl- concentration. MQAE has a pH-independent fluorescence intensity basically at a Cl- concentration <50 nM. MQAE has high water solubility and cell permeability. Ex/Em=350/460 nm
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
