Labeling of dopamine transporter (DAT) with ligand conjugated-QDots in live HeLa cells. (Left) Streptavidin-conjugated QDots were used to label DATs previously exposed to a biotinylated, PEGylated cocaine analog. (Upright) chemical structure of the DAT ligand used in the study. (A1) QDot labeling of membrane DATs in a live HeLa cell. (B1) QDot-bound DATs underwent acute redistribution from the plasma membrane to intracellular compartments as a result of protein kinase C (PKC) activation. (Reprinted with permission from Ref 48.
