Heparinase I is useful in many applications (usually with heparinase II and heparinase III), for example:

  • For the neutralization of heparin in blood and plasma samples before analysis.
  • For similar in vitro neutralization of low molecular weight heparins.
  • As integral part of in vitro diagnostic tests for the neutralization of heparin (blood clotting tests, platelet tests).
  • In blood collection tubes for the neutralization of heparin.
  • For the preparation of low molecular weight heparins from unfractionated heparin.
  • As a research reagent (glycosaminoglycan degradation).
  • For the preparation of disaccharides of heparin and the preparation of oligosaccharide libraries.
