(noun)

A fibrinolytic molecule expressed on endothelial cells or produced as a blood thinner medicine. It prevents activation of platelets and clotting factors.

Examples of heparin in the following topics:

  • Anticoagulants

    • Where an immediate effect is required, heparin must be given concomitantly.
    • Heparin is a biological substance usually made from pig intestines.
    • Heparin can be used in vivo (by injection), and also in vitro to prevent blood or plasma clotting in or on medical devices.
    • Vacutainer brand test tubes containing heparin are usually colored green.
  • Iron-Binding Proteins

    • Lactoferrin interacts with DNA and RNA, polysaccharides and heparin, and shows some of its biological functions in complexes with these ligands.
  • Withdrawing Blood

    • The gold tube contains a clot activator and gel for serum separation, the green tube contains heparin for clinical chemistry, and the red tube contains a clot activator.
  • Diphtheria

    • Fragment B is a recognition subunit that gains the toxin entry into the host cell by binding to the EGF-like domain of heparin-binding EGF-like growth factor (HB-EGF) on the cell surface.
  • Teratogens

    • Women with indications for warfarin therapy should either abstain from pregnancy or switch to low molecular weight heparins.
  • Blood Plasma

    • Normally, anticoagulants and fibrinolytics in the plasma, such as plasmin and heparin, break up fibrin clots and inactivate thrombin.
  • Fibrinolysis

    • Heparin is a fast-acting anticoagulant produced by the body and used as a drug which inhibits the activity of thrombin.
  • Transient Ischemic Attacks

    • Example drugs used to prevent future TIAs include anti-coagulant medications, like heparin and warfarin, and anti-platelet medications such as aspirin.
  • Overview of Hemostasis

    • The endothelial cells of intact vessels prevent clotting by expressing a fibrinolytic heparin molecule and thrombomodulin, which prevents platelet aggregation and stops the coagulation cascade with nitric oxide and prostacyclin.
