Targeting of 20% aminoQD–SA conjugates to EGFR on live cells. EGFR expressing cells are indicated by blue fluorescent protein (BFP) cotransfection marker. (Top row) QD558 channel. (Bottom row) BFP merged with DIC channel. (Left) EGFR-transfected COS7 cells treated with biotinylated EGF and stained with aminoQD–SA. (Right) Control experiment in which aminoQD–SA was blocked with excess free biotin before application to cells. Scale bar, 10 µm.
