title: Age-dependent changes in monkey lenticular gangliosides.
abstract: The content, composition, and distribution of gangliosides were examined in the lenses of normal rhesus monkeys aged 6-16 years. Gangliosides were isolated by organic solvent extraction. DEAE-Sephadex ion-exchange column chromatography, and thin-layer chromatography (TLC). Ganglioside contents determined by the thiobarbituric acid method increased in the lens with aging. TLC analysis of gangliosides showed a much more complex pattern with aging, and the predominant gangliosides were tentatively identified as GM3, GM1, and GD1a. Individual lenticular gangliosides were identified by TLC-immunostaining procedures using anti-GM1 and anti-asialoGM1 antisera.
