LRIG3 in Human Cervical Cancer Tissue. LRIG3 was detected in immersion fixed paraffin-embedded sections of human cervical cancer tissue using Goat Anti-Human LRIG3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3495) at 3 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). Specific staining was localized to cytoplasm of cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections .
