Sialosyllactotetraosylceramide, 3′‐isoLM1, a Ganglioside of the Lactotetraose Series Isolated from Normal Human Infant Brain

Abstract
A ganglioside antigen was detected in infant human brains by the monoclonal antibody C-50. Structural analysis of the isolated ganglioside antigen showed it to be 3''-isoLM1, sialosyllactotetraosylceramide. The concentration of this ganglioside in human infant brain was 0.5 nmol/g.
