 | | Using this quantitative analysis procedure, percentages of disaccharide compositions for heparins from porcine and bovine intestinal mucosa and heparan sulfate from bovine kidney were determined. | | | The disaccharide compositions determined for heparins from porcine and bovine intestinal mucosa and heparan sulfate from bovine kidney, using our quantitative analysis method, were in accordance with those previously reported. | | | However, although a qualitative assignment of which disaccharides are present in a digest is useful, quantitative information is more often required for a complete compositional analysis and further characterization of the heparin or HS. |
