Carcinoembryonic antigen-related cell adhesion molecule 8 (CEACAM8) also known as CD66b (Cluster of Differentiation 66b), is a member of the carcinoembryonic antigen (CEA) gene family. Its main function is cell adhesion, cell migration, and pathogen binding. Use CEACAM8 is expressed exclusively on granulocytes and used as granulocyte marker.
