characterization of the specificity of these antibodies indicated that they recognize determinants present in the keratan sulfate glycosaminoglycan chain and on chondroitin sulfate oligosaccharide stubs attached to the proteoglycan core protein after chondroitinase digestion of the proteoglycan ( i.e. , delta-unsaturated 4- and 6-sulfated and unsulfated chondroitin sulfate on the proteoglycan core ) .
