Neurocan in Human Brain. Neurocan was detected in immersion fixed paraffin-embedded sections of human brain using Sheep Anti-Human Neurocan Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6508) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019 ) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm of neurons. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections .
