Western blot shows lysates of LNCaP human prostate cancer cell line, HeLa human cervical epithelial carcinoma cell line and human liver tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human CEACAM‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4478) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for CEACAM‑7 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
CEACAM‑7 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Sheep Anti-Human CEACAM‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4478) at 3 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 cell surfaces of cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
