Carbohydrates 33-45 fucosyltransferase 4 Homo sapiens 16-19 7693048-9 1993 Our results suggest that various molecular species of sialyl Lex antigens are present on carbohydrate side chains of cellular glycoproteins, and that helper memory T cells express a distinct type of sialyl Lex antigen that is defined by 2F3 but is not efficiently detected by other typical anti-sialyl Lex antibodies.
