Figure 10. Increased PFT binding intensity over VFF18 in PCa human TMA.

Immunohistofluorescence confocal images of a T3N2M1 (grade III) TMA sample stained by VFF18 mAb (A), PFT peptide (B), and Scr1 peptide (C). A difference in binding intensity was observed between samples stained by VFF18 (A) and PFT (B). The cell nuclei were stained by DAPI (blue), the bound VFF18 was detected by PE conjugated secondary Ab (red), and the bound biotinylated peptides were detected by PE conjugated streptavidin (red). Scale bar, 150 μm.
