A GM1 ganglioside derivative bearing a photoreactive nitrophenyl azide group and tritium labeled at the acetyl group of N-acetylneuraminic acid, has been administered to cultured human fibroblasts. With photolabeling experiments we found that a portion of the ganglioside in the cell cytosol was associated with a soluble protein of about 30 kDa.

Abstract
A GM1 ganglioside derivative bearing a photoreactive nitrophenyl azide group and tritium labeled at the acetyl group of N-acetylneuraminic acid, has been administered to cultured human fibroblasts. With photolabeling experiments we found that a portion of the ganglioside in the cell cytosol was associated with a soluble protein of about 30 kDa.
