FluoZin™-1, Tripotassium Salt, cell impermeant

Back to top


The FluoZin™-1 and FluoZin™-2 indicators are designed to detect Zn2+ concentrations that are present in synaptic vesicles and released in response to electrical stimulation or excitotoxic agonists. Based on the N-(2-methoxyphenyl)iminodiacetate chelator, these indicators are designed for detection of Zn2+ in the 0-100 µM range with minimal interfering Ca2+ sensitivity. FluoZin™ indicators are offered in cell-permeant and cell-impermeant forms.

Fluorescent Zinc Indicators Specifications:
• Label (Ex/Em): FluoZin™-1 (~495/515 nm)
• Kd (Zn2+) (in buffer): ~8 µM
• Lyophilized product may be dissolved in distilled water or aqueous buffer for use
• Product is typically loaded into cells using microinjection or diffusion from patch pipette

Find Fluorescent Indicators for Zinc and Other Metal Ions
We offer a number of fluorescent indicators to determine polyvalent cation concentrations inside cells, to follow metal ion transport through ion channels, to make measurements in environmental samples, and more. Review Fluorescent Indicators for Zn2+ and Other Metal Ions-Section 19.7 in the Molecular Probes® Handbook for more information on these products.
