A GRANULOCYTE REACTIVE MONOCLONAL-ANTIBODY, 1G10, IDENTIFIES THE GAL-BETA-1-4(FUC-ALPHA-1-3)GLCNAC (X-DETERMINANT) EXPRESSED IN HL-60 CELLS ON BOTH GLYCOLIPID AND GLYCOPROTEIN MOLECULES

Abstract
1G10, a monoclonal IgM antibody that identifies a differentiation antigen on human granulocytes and a subpopulation of monocytes, was found to react specifically with glycosphingolipids bearing the Gal.beta.1-4(Fuc.alpha.1-3)GlcNAc hapten (X determinant). This carbohydrate determinant was found on both glycolipid and glycoprotein molecules isolated from HL-60 cells (a [human] promyelocytic leukemia cell line). Thus, this highly conserved carbohydrate-defined determinant previously described on mouse embryonic and mouse and human carcinoma cells is also expressed as a tissue-specific differentiation antigen on normal human granulocytes.
