Anti-CEA cell adhesion molecule 8 antibodies are used for the immunodetection of the protein encoded by the CEACAM8 gene. In humans, the canonical protein has a reported length of 349 amino acid residues and a mass of 38.2 kDa. Its subcellular localization is in the cell membrane. It is reported to be expressed in leukocytes of chronic myeloid Leukemia patients and bone marrow. A member of the CEA protein family, it is known to be involved with immune response pathways. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include CD67, CGM6, NCA-95, carcinoembryonic antigen-related cell adhesion molecule 8, CD67 antigen, and CD66b. Gene orthologs have been identified in the mouse and chimpanzee species.
