Undersulfated urinary glycosaminoglycans in preterm newborns. 1978

G V Coppa, and O Gabrielli, and A Maiorana, and S Sani, and A Benincasa, and M Belsito, and U Montali

The glycosaminoglycans (GAG) isolated from pooled urine of preterm newborns were fractionated by stepwise elution from a Dowex 1-X2 column. Analytical reactions, cellulose acetate electrophoresis and enzymatic digestions with chondroitinases and testicular hyaluronidase were performed on each fraction. Chondroitin-4-sulfate and chondroitin-6-sulfate constitute about 60% of urinary GAG; heparan sulfate amounts to about 20%, while chondroitin represents 12% of total GAG; dermatan sulfate, hyaluronic acid and keratan sulfate are present in small traces. Approximately 30% of the total is constituted by nonsulfated GAG.

D002845 Chromatography Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts. Chromatographies
