pH responsive fluorescent false neurotransmitter (FFN). Selective dopamine transporter (DAT) and VMAT2 substrate. Exhibits no significant binding to a panel of 38 CNS receptors, including dopamine and serotonin receptors. Inhibits dopamine uptake. Excitation maxima are 340 nm at pH 5 and 370 nm at pH 7.5. Emission maximum is 435 nm at both pH 5 and 7.5.
