Abstract
Crude clinically used heparin preparations having a low specific activity, for example, about 130 heparin units per milligram are purified by contacting such liquid crude heparin preparations with a gel matrix complexed with (i.e. having linked to it) antithrombin or inter-alpha-trypsin inhibitor as a heparin-binding plasma protein, and then desorbing or eluting the heparin from the antithrombin or inter-alpha-trypsin inhibitor complexed gel matrix as with an applicable buffer, removing any salt in the solution with the heparin by gel filtration and then drying the heparin as by lyophilization.
