Subcellular localization of CD66, CD67, and NCA in human neutrophils.


CD66 and CD67 are granulocyte-specific activation antigens; their surface expression is up-regulated when neutrophils are activated. CD66 antibodies recognize an approximately 180-kd neutrophil surface protein that is also recognized by anti-carcinoembryonic antigen (CEA) antibodies and is therefore a nonspecific cross-reacting antigen (NCA). CD67… (More)
