Human embryonic kidney 293 cells (HEK-293) transfected with the corresponding cDNA of norepinephrine transporter (NET) (HEK-hNET) and serotonin transporter (HEK-hSERT) specifically take up (a) labeled norepinephrine ([3H]-NE) (n = 3) or (b) labeled 5-hydroxytryptamine ([3H]-5-HT), respectively, but human embryonic kidney (HEK 293) cells (n = 3) do not. * p < 0.05.
