Intercellular glycosaminoglycans have been isolated from normal and neoplastic mammalian tissues. They have been characterized by cellulose acetate electrophoresis and by chemical and enzymatic degradation. The electrophoretic pattern of the intercellular glycosaminoglycans is tissue specific. Further, the electrophoretic patterns of all spontaneous neoplasias analyzed differ significantly from patterns obtained from the tissues of origin.
