Anti-My-28 is an IgM κ monoclonal antibody produced by a hybridoma prepared from spleen cells of a mouse immunized with normal human granulocytes. By immunofluorescence it binds to human granulocytes but not to monocyes and lymphocytes. However, after treating cells with neuramindase, the antibody also binds to lymphocytes and monocytes and to many leukemic cell lines and patient leukemic blast cells. Anti-My-28 binds to several neutral glycolipids and desialylated gangliosides of leukocytes and erythrocytes as detected by radioimmunoassay and immunostaining of thin-layer chromatograms. It recognizes a sugar sequence in lacto-N-neotetraose, Ga1β1-4GlcNacβ1-3Galβ1-4Glc. This tetrasaccharide occurs in the glycolipids paragloboside and sialosylparagloboside, and its distal trisaccharide sequence is found in higher glycolipids and in glycoproteins.
