Figure 8. PFT staining of v6A3 xenografted tumor tissue.

(A) Confocal images of paraffin-embedded v6A3 tumor xenografts from mice. The SORE6-GFP positive cells (green) were stained by FITC-conjugated anti-GFP Ab and cell nuclei were stained by DAPI (blue). Scale bar, 200 μm. (B) Confocal images of PFT staining in v6A3 xenografted tumor tissue. Bound biotinylated PFT was detected by PE conjugated streptavidin (red). The cell nuclei were stained by DAPI (blue) and SORE6-GFP positive cells (green) were stained by FITC conjugated anti-GFP Ab. Scale bar, 50 μm.
