In vitro labeling of MGC80-3 cells with CC49-QDs Ab probe and primary QDs. (A1/B1/C1/D1) The cell nucleus was stained with DAPI. (A2) MGC80-3 cells labeled with QDs. (B2) MGC80-3 cells labeled with CC49-QDs. (C2) MGC80-3 cells labeled with CC49-QDs after blocked with free CC49. (D2) MGC80-3 cells labeled with fluorescent secondary antibody. A3/B3/C3/D3 were merged with A1 and A2, B1 and B2, C1 and C2, D1 and D2, respectively.
