DPP6 was detected in immersion fixed paraffin-embedded sections of human spinal cord using Goat Anti-Human DPP6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2360) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling when primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.
