Heparin Activity

SummaryPreparations were made of rabbit liver globulin by the method of Jaques for heparinase and their effect on heparin studied. The results confirmed the observations of a progressive loss of anticoagulant activity with globulin in 0.9% saline, of a loss of metachromatic activity after phenol extraction and the reversal of the latter by alkali. The latter observations were due to the solubility in phenol of heparin on combination with protein. With suitable preparations, a decrease in anticoagulant activity without decrease in metachromatic activity was observed, i.e. conversion of heparin to uroheparin. Loss of heparin due to combination with protein and resulting precipitation, solubility in phenol, etc. followed a protein pH-dissociation curve. Loss of heparin anticoagulant activity due to heparinase was maximal at pH 5.4. No loss of heparin occurred at pH values more acid than 5 or more alkaline than 7.
