Tissue plasminogen activator is a protein involved in the breakdown of blood clots. Specifically, it is a serine protease (EC 3.4.21.68) found on endothelial cells, the cells that line the blood vessels. As an enzyme, it catalyzes the conversion of plasminogen to plasmin, the major enzyme responsible for clot breakdown. Because it works on the clotting system, tPA is used in clinical medicine to treat only embolic or thrombolytic stroke. Use is contraindicated in hemorrhagic stroke and head trauma.The classic role of tPA is in the clotting system. Specifically, tPA catalyzes the conversion of plasminogen into plasmin. It does so by cleaving the single-chained plasminogen into two chains. These two chains are linked by a disulfide bond and the resulting molecule is called plasmin.

Rabbit Tissue-type Plasiminogen Actilyse (t-PA) ELISA Kit employs a two-site sandwich ELISA to quantitate t-PA in samples. An antibody specific for t-PA has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyt-PA present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for t-PA is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of t-PA bound in the initial step. The color development is stopped and the intensity of the color is measured.
