Characterization of mOct2

	K m (μm)	V max (pmol·mg protein−1·min−1)	V max/K m (μL·mg protein−1·min−1)
Serotonin	313 ± 68	600 ± 39	1.9
Dopamine	ND	ND	ND
Noradrenaline	ND	ND	ND
Histamine	111 ± 29	651 ± 38	5.9

ND, not determined. Individual transport assays were performed in triplicate (three wells were analyzed for each group per trial). The results were confirmed at least two times in separate experiments using different cryopreserved cell vials. The results shown are representative of experiments performed.
