Detection of Human CEACAM‑7 by Western Blot. 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 in Human Colon Cancer Tissue. 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.

Background: CEACAM-7
CEACAM-7 (carcinoembryonic antigen cell adhesion molecule 7; also CGM2) is a 40‑45 kDa member of the CEACAM subfamily of the CEA family of proteins. It has a restricted expression pattern, being found on epithelium of the colon, appendix and pancreatic ducts. It is markedly down‑regulated in colon carcinoma. Mature human CEACAM-7 is a 209 amino acid (aa), GPI-linked glycoprotein. It contains one V-type (aa 36‑142) and one C2-type (aa 146‑233) Ig-like domain, plus a 21 aa C‑terminal propeptide. One alternate splice form exists that shows a deletion of aa 143‑235. No definitive rodent CEACAM-7 has been reported.
