FFN246 is a fluorescent, dual substrate of serotonin transporter (SERT) probe and vesicular monoamine transporter 2 (VMAT2) with excitation and emission spectra 392/427 nm. FFN246 can be used for labeling serotonergic neurons in mouse brain tissue through SERT-dependent accumulation.
FFN246 (2.5-20 μM, 30 mins) can be used for direct examination of serotonin transporter (SERT) activity and SERT inhibitors in 96-well cell culture assays, as well as specific labeling of serotonergic neurons of the dorsal raphe nucleus in the living tissue of acute mouse brain slices[1].FFN246 (20 μM, 30 mins) effectively traces serotonin uptake and packaging in the soma of serotonergic neurons[1].
