Tissue-type plasminogen activator, short name tPA, is a protein that facilitates the breakdown of blood clots. It acts as an enzyme to convert plasminogen into its active form plasmin, the major enzyme responsible for clot breakdown. It is a serine protease (EC 3.4.21.68) found on endothelial cells lining the blood vessels.
Alteplase, sold under the brand name Activase among others, is a biosynthetic form of human tissue-type plasminogen activator (t-PA). It is a thrombolytic medication used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure, and blocked central venous catheter.

Plasminogen activator inhibitor-1 is a serine protease, synthesized by endothelial cells, that specifically inhibits tissue plasminogen activator (tPA) and urokinase (uPA). Tissue plasminogen activator and urokinase are the activators of plasminogen and result in the breakdown of blood clots (fibrinolysis). [4]
Tenecteplase, sold under the trade names TNKase, Metalyse and Elaxim, is an enzyme used as a thrombolytic drug. Tenecteplase is a tissue plasminogen activator (tPA) produced by recombinant DNA technology using an established mammalian cell line (Chinese hamster ovary cells).
PAI-1 is a serine protease inhibitor that functions as the principal inhibitor of tissue-type plasminogen activator (tPA) and urokinase (uPA), the activators of plasminogen and hence fibrinolysis (the physiological breakdown of blood clots). It is a serine protease inhibitor (serpin) protein (SERPINE1).
Tissue plasminogen activator (also known as tPA, t-PA, rtPA, Activase, or Alteplase or Actilyse) [5] is a drug that breaks down blood clots. It was first approved in 1996, yet this drug has no generic competition.
Tissue plasminogen activator (TPA) is a serine protease occurring in animals including humans. Human-identical TPA (produced industrially by genetically recombinant microorganisms) has an established medical use in the treatment of ischemic stroke: by its proteolytic activity it enables the action of another enzyme (plasmin), which breaks down the protein (fibrin) of blood clots.
All currently approved thrombolytic drugs are biologics, either derived from Streptococcus species, or, more recently, using recombinant biotechnology whereby tPA is manufactured using cell culture, resulting in a recombinant tissue plasminogen activator or rtPA. [citation needed] Some fibrinolytics are: Streptokinase (Kabikinase) [14 ...
