Abstract
Crude glycosaminoglycans (GAG) separated from normal human urine by cetylpyridinium chloride-precipitation were fractionated with ethanol. The resulting fractions were then examined by electrophoresis on cellulose acetate membranes before and after enzymatic digestions and nitrous acid treatment. Analytical data for these fractions and the electrophoretograms suggested that ethanol-fractionation was useful to separate roughly chondroitin sulfate A, C-type GAG and heparan sulfate in human urine.
