Heparan sulfate purified from isolated hepatocytes was digested with heparin lyases I, II, and III. The resulting disaccharides were derivatized with isotopically labeled aniline and quantified by mass spectrometry (see methods). Disaccharides are designated using the code established in 40. Those containing the letter S contain a N-sulfate group.
