abstract：:We have previously identified a molecule on the T cell surface, which, in addition to CD2 is involved in the rosette phenomenon. This is a 32-kDa single polypeptide chain which we have termed E2. The studies reported here show striking patterns on the glycosylation status of E2. It is a heavily sialylated and glycosyl...
