Figure 9. Detection of CD44v6 in PCa human TMAs using PFT peptide.

Immunohistofluorescence confocal images of human TMAs. Shown are representative images of CD44v6 positive (A, C and E) and PFT positive (B, D and F) staining (red) observed in human PCa samples with different staging and grading, including T2N0M0 (grade II) (A and B), T4N1M1 (grade III) (C and D), and lymph nodes metastasis (E and F). The cell nuclei were stained by DAPI (blue), the bound VFF18 was detected by PE conjugated secondary Ab (red), and the bound biotinylated PFT was detected by PE conjugated streptavidin (red). Scale bar, 150 μm.
