In vitro labeling of GES-1 cells with CC49-QDs Ab probe and primary QDs. (E1/F1/G1/H1) The cell nucleus was stained with DAPI. (E2) GES-1 cells labeled with QDs. (F2) GES-1 cells labeled with CC49-QDs. (G2) GES-1 cells labeled with CC49-QDs after blocked with free CC49. (H2) GES-1 cells labeled with fluorescent secondary antibody. E3/F3/G3/H3 were merged with E1 and E2, F1 and F2, G1 and G2, H1 and H2, respectively.
