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.
