PQD-antibody probes for targeted imaging of in vitro MGC803 cells. (a- d) Bright-field and fluorescence images of gastric cancer MGC803 cell line; the cells were incubated at 4°C with PQD-antibody probes (BRCAA1 and Her2) in 1% BSA overnight (similarly hereinafter), excited with 450 and 510 nm for Her2 and BRCAA1 probes, respectively, and exposure time was 15 s. (e- h) Bright-field and fluorescence images of human fetal gastric epithelial GES-1 cell line; fluorescence exposure time was 60 s. Scale bars are 25 μm.
