Detection of Human CEACAM‑8/CD66b by Western Blot. Western blot shows lysates of human peripheral blood mononuclear cells (PBMC) and human peripheral blood granulocytes. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human CEACAM‑8/CD66b Monoclonal Antibody (Catalog # MAB4246) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for CEACAM‑8/CD66b at approximately 100 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of CEACAM‑8/CD66b in Human Blood Granulocytes by Flow Cytometry. Human peripheral blood granulocytes were stained with Mouse Anti-Human CEACAM‑8/CD66b Monoclonal Antibody (Catalog # MAB4246, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B).

CEACAM-8 (Carcinoembryonic Antigen-related Cell Adhesion Molecule 8), also known as CD66b, CD67 and NCA-95, is a 90 kDa member of the CEACAM subfamily of the CEA family of proteins. It is expressed by neutrophils and eosinophils, and serves as a binding partner for CEACAM-6 and Galectin-3. Mature human CEACAM-8 is a 287 amino acid GPI-linked glycoprotein. It contains one V-type and two C2-type Ig-like domains. No definitive rodent CEACAM-8 has been reported.
