Ganglioside compositions of erythrocytes from various strains of inbred mice. Ocurrence of sialosylgalactosylceramide in red blood cells of inbred mice.

The gangliosides from the erythrocytes of various strains of inbred mice were analyzed. The ganglioside compositions differed in different strains and the strains could be divided into 4 types on the basis of this difference. The main ganglioside is GM4 or sialosyl galactosyl ceramide in Type 1, and unidentified ganglioside in Type 2, GM4 and GM2 in almost equal amounts in Type 3, and GM2 in Type 4.
