    摘要: A method for preparing de-N-acylated forms of an N-acyl sugar-containing glycosphingolipid and lyso forms of glycosphingolipid comprising hydrolyzing the glycosphingolipids under mild alkaline conditions such that the N-acyl group of the sugar moiety is preferentially hydrolyzed. Substantially pure gangliosides containing de-N-acetyl-sialic acid isolated from natural sources. A culture medium for stimulating growth of human and animal cells comprising: essential nutrients for cell growth, and a cell growth stimulatory amount of one or more gangliosides containing de-N-acetyl-sialic acid. A method for stimulating growth of human and animal cells cultured in vitro with a cell growth stimulatory amount of one or more gangliosides containing de-N-acetyl-sialic acid. A medicament and method for stimulating or inhibiting growth of human and animal cells by stimulating or inhibiting the production of growth stimulators selected from the group consisting of gangliosides containing de-N-acetyl-sialic acid, substances that promote synthesis of gangliosides containing de-N-acetyl-sialic acid and pharmaceutically acceptable salts thereof.

    摘要: The invention provides a novel species of α-1,3-fucosyltransferase expressed by a gene cloned from animal cells, a cDNA coding for the α-1,3-fucosyltransferase, a method of detecting, or inhibiting the production of, the α-1,3-fucosyltransferase which involves the use of the cDNA, a recombinant vector containing the DNA as an insert, a cell harboring the recombinant vector, and a method of producing same. The α-1,3-fucosyltransferase of the invention is useful in the production of carbohydrate chains having useful physiological activity, for example sialyl Lewis x, and modifications thereof.
