human primary germ cell tumors were analyzed for the presence of the ganglioside gm2 using three specific monoclonal antibodies which can distinguish the molecular species of the sialic acid moiety : the antibody mk1-16 is specific for n-acetyl gm2 , mk2-34 is specific for n-glycolyl gm2 , and mk1-17 detects both n-acetyl and n-glycolyl gm2 .
