Scientific Data Images for Human CEACAM-7 Antibody
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.Applications for Human CEACAM-7 Antibody

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.
