Standards or test samples are added to the wells and subsequently a TPA specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of TPA captured in plate.\u003cbr\u003e\nThe entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.\u003cbr\u003e\nAssay Specificity\u003cbr\u003e\nOur ELISA kits are rigorously validated to ensure the highest level of consistency and reproducibility.

This reaction occurs at the surface of a fibrin clot leading to clot degradation a process known as fibrinolysis. tPA has a molecular mass of approximately 70 kDa. It is mainly expressed in vascular endothelial cells and is released into the bloodstream in response to stimuli such as circulatory stasis or endothelial damage.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nTPA plays a critical role in thrombolysis by breaking down blood clots into their soluble components. It regulates plasminogen function by cleaving this zymogen to yield the active protease plasmin. This function makes tPA integral in maintaining hemostasis and it does not form a part of a larger protein complex. The activity and the regulation of tPA are important for preventing pathologic clotting which can lead to cardiovascular complications.\u003cbr\u003e\nPathways\u003cbr\u003e\nTPA is central to the fibrinolytic pathway. This pathway facilitates the conversion of plasminogen to plasmin enabling clot resolution. In addition tPA interacts with other proteins such as urokinase plasminogen activator (uPA) and inhibitors like plasminogen activator inhibitor-1 (PAI-1). The balance between tPA and its inhibitors is important for the regulation of fibrinolytic activity impacting hemostatic and thrombotic events.\u003cbr\u003e\nTPA connects closely with conditions like stroke and myocardial infarction due to its thrombolytic properties. In ischemic stroke excessive or insufficient tPA activity can disrupt normal blood flow leading to tissue damage. Additionally in myocardial infarction tPA's role in breaking down clots proves important for restoring coronary blood flow. It is also linked with proteins like fibrinogen as they serve as substrates in the clot degradation process and with PAI-1 which modulates its activity and influences disease progression.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843620622505,"sku":"ab108914","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab108914","provider":"Iright","version":"1.0","type":"link"}
