Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the carboxy terminus of human CEACAM8 protein.
Carcinoembryonic antigen-related cell adhesion molecule 8 (CEACAM8), also known as CD66b, is a member of the CEA-related cell-adhesion molecule (CEACAM) family (1). CEACAMs bind to themselves and other family members to carry out numerous cellular functions, including proliferation, signaling, differentiation, tumor suppression, and survival (2). CEACAM8 is a single-chain, glycosylphosphatidylinositol (GPI)-anchored, highly glycosylated protein that under normal conditions is expressed almost exclusively on granulocytes (3). Heterophilic interactions of CEACAM8 with other surface molecules, such as CEACAM6, have been shown to be involved in regulating cell adhesion in a calcium-independent manner (4). As such, CEACAM8 has demonstrated utility as a marker of neutrophil and eosinophil activation (5,6) and in pathological conditions is shown to be highly expressed in primary myelofibrosis and acute lymphoblastic leukemias (7,8). Assessment of CEACAM8 positive tumor-infiltrating neutrophils has demonstrated value as a prognostic factor in multiple cancer types (9,10).
