Siglec-9 peptide binds to vascular adhesion protein 1 (VAP-1)-positive vessels in human inflamed synovium. Left panel, binding of biotinylated Siglec-9 peptide (red). Middle panel, VAP-1-positive vessels detected by fluorescein-conjugated anti-VAP-1 monoclonal antibody (green). Right panel: merge. Inset, negative control staining. Arrows indicate some double-positive vessels. Scale bar is 100 μm
