Species of 67Ga-binding acid mucopolysaccharide in liver.

It was determined from measuring neutral saccharide in the structure that the principal 67Ga-binding acid mucopolysaccharide in liver was keratan sulfate and/or keratan polysulfate. On the other hand, it was clarified from the results of mucopolysaccharase treatment that the main 67Ga-binding acid mucopolysaccharide in liver was not either one of keratan sulfate, heparan sulfate, heparin, chondroitin sulfate A, B and C. Based on the present results, it was deduced that the main 67Ga-binding acid mucopolysaccharide in liver was keratan polysulfate.
