The procedures for the preparation of radioactive and photoactivable ganglioside derivatives have been continuously developed from 1989, when for the first time the synthesis of photoactivable tritium labeled GM1 ganglioside was presented.

The use of these ganglioside derivatives to study the ganglioside-protein interactions and to identify proteins that specifically interact with gangliosides (including GPI-anchored proteins of the outer membrane leaflet, proteins anchored to the cytoplasmic side of the plasma membrane through a fatty acyl chain, transmembrane proteins, and soluble cytoplasmic proteins) is discussed.

Abstract
The procedures for the preparation of radioactive and photoactivable ganglioside derivatives have been continuously developed from 1989, when for the first time the synthesis of photoactivable tritium labeled GM1 ganglioside was presented. We described previously the synthesis of photoactivable derivatives of GM3 and GM1 gangliosides, tritium-labeled at acetyl group of sugar units, and of photoactivable GM1 and GD1b gangliosides, tritium-labeled at position 6 of the external galactose. These procedures are reviewed in detail in the present paper. The use of these ganglioside derivatives to study the ganglioside-protein interactions and to identify proteins that specifically interact with gangliosides (including GPI-anchored proteins of the outer membrane leaflet, proteins anchored to the cytoplasmic side of the plasma membrane through a fatty acyl chain, transmembrane proteins, and soluble cytoplasmic proteins) is discussed.Pubblicazioni consigliate
