title: Fractionation and isolation of heparan sulfates using poly-L-lysine-Sepharose.
abstract: A simple procedure for the isolation of heparan sulfates from pig lung using a poly-L-lysine-Sepharose column is described. Glycosaminoglycans are absorbed on poly-L-lysine-Sepharose at pH 7.5 and eluted with an NaCl linear gradient in the following order: hyaluronic acid (0.32 M NaCl), chondroitin (0.36 M NaCl), keratan sulfate (0.80 M NaCl), chondroitin 4-sulfate (0.86 M NaCl), chondroitin 6-sulfate (0.95 M NaCl), dermatan sulfate (0.91 M NaCl), heparan sulfate (1.2 M NaCl), and heparin (1.35 M NaCl). Based on these observations, isolation of heparan sulfate from pig lung crude heparan sulfate fractions which contain chondroitin sulfates and dermatan sulfate was attempted, using this chromatographic technique.
