Disialoganglioside GDla of rat brain subcellular particles during development

The increase observed in the amount of the disialoganglioside GDlof the rat cerebrum during development between 21 and 81 days of age accounted for nearly 40% of the overall increase in total ganglioside in the tissue during the same period. Subcellular fractionation showed the microsomal fraction to contribute by far the most towards this increase in Cerebral ganglioside GDla. It is suggested that microsomal ganglioside GDla may serve as a marker for dendritic arborization in the rat cerebrum.
