Recognizes a (Mr 110kDa) carbohydrate molecule on myeloid cells. This surface antigen is associated with myelin-associated glycoprotein (MAG).(1) This antibody blocks binding of HNK -1 (Leu. 7) antibody.(3) The CD57 antigen is present on 15-20% of normal peripheral blood mononuclear cells. It is expressed on a subset of natural killer cells (60%) and on a subset of T -lymphocytes. This carbohydrate is also present on N-CAM in the nervous system.
