Surfaces of human embryo fibroblasts in vitro were reacted with stain and lectin probes for carbohydrate moeities either after or in the absence of treatment with low concentrations of surface-active enzymes and EDTA. Only testicular hyaluronidase significantly suppressed affinity-binding of all three agents, suggesting that acidic glycosaminoglycans are principle components of the cell's exterior.
