"We used GM2/GD2 synthase (B4galnt1)-deficient mice to immunize by liposomes embedded with GD1alpha or acidic glycolipid fractions from brain of St3gal5-deficient mice. Specificities of established mAbs as analyzed by enzyme-linked immunosorbent assay and thin-layer chromatography-immunostaining were very high among various gangliosides."xsd:string
