The present study was undertaken in order to characterize further the glycosaminoglycans of normal human plasma. Coagulation factor IX concentrate prepared from undiluted plasma by DEAE-Sephadex chromatography was used as the starting material. The concentrate was subjected to proteolytic treatment with papain and pronase, deproteinised with trichloroacetic acid, dialysed and passed through an AG 1 X 2 anion-exchange column. Glycosaminoglycans were eluted stepwise from the column with NaC1. The sole glycosaminoglycan obtained was an undersulphated chondroitin-4-sulphate which was identified by chemical analyses, digestibility with testicular hyaluronidase, electrophoretic behaviour and infrared spectrum. Gel-exclusion chromatography indicated a molecular weight of 17 000 for the compound. The undersulphated chondroitin-4-sulphate was calculated to represent at least 80% of the macromolecular glycosaminoglycans present in normal human plasma and to occur in a concentration of approx. 3 mg hexuronate per 1 of plasma.
