Antibodies to human CD17 react with lactosylceramide which is expressed on granulocytes, monocytes, platelets, and basophils (1). CD17 expression is downmodulated on activated granulocytes. CD17 is an important componant in CD11b/CD18 mediated phagocytosis of microbes (2).
Isotype: Murine IgM
Immunogen: Human beta-2 microglobulin associated proteins from a detergent lysate of PBL
Specificity: Antibody Huly-m13 requires CD17 on human myeloid cells. It does not recognize mouse LacCer (6).
