FluoZin™-3, Tetrapotassium Salt, cell impermeant

The FluoZin™-3 indicator is a Zn²⁺-selective indicator with a structure that resembles fluo-4. FluoZin™-3 exhibits high Zn²⁺-binding affinity that is unperturbed by Ca²⁺ concentrations up to at least 1 μM. In addition, FluoZin™-3 exhibits a >50-fold increase in fluorescence in response to saturating levels of Zn²⁺. Although imaging applications of FluoZin™-3 are predominant, cell-based microplate assays and flow cytometry protocols have also been developed. FluoZin™-3 indicator is available in a cell-permeant and a cell-impermeant form.
