Abstract/OtherAbstract:
The sialic acid content of gangliosides from pig spleen lymphocytes was studied by thin-layer chromatography. N-glycolylneuraminic acid and N-acetylneuraminic acid were detected for the first time in this material as the major sialic acids. In addition, two other sialic acids, tentatively designated O-acetylated sialic acids, according to their RF values on cellulose plates, were also found. We have detected several gangliosides showing a retarded migration pattern in two dimensional thin-layer chromatography with an intermediate ammonia treatment. One of these gangliosides could be an O-acetylated derivative of the disialoganglioside GD3, since after de-O-acetyation it co-migrates with GD3. Another ganglioside co-migrated with GM2 before the alkaline treatment; however, after the treatment it was also retarded and co-migrates with GD3.
