Example of human Tissue Plasminogen Activator (TPA) standard curve in Sample Diluent NS.
The Tissue Plasminogen Activator (TPA) standard curve was prepared as described in Section 10. Raw data generated on SpectraMax M4 Multi-Mode Microplate Reader is shown in the table. Background-subtracted data values (mean +/- SD) are graphed.

Interpolated concentrations of TPA in human serum and plasma.
The concentrations of TPA were measured in duplicate and interpolated from the TPA standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean TPA concentration was determined to be 4,710 pg/mL in serum and 4,270 pg/mL in plasma (heparin).

Comparison of secreted TPA in unstimulated and PHA-stimulated human PBMC.
PBMC were grown in the absence or presence of phytohemagglutinin (PHA) for 2 days. TPA was measured in 4-fold diluted cell culture supernatants of unstimulated and PHA stimulated PBMC. Measured values were interpolated from the TPA Standard Curve diluted in Sample Diluent NS and DF corrected. Mean +/-SD, n=2, are graphed.

Interpolated concentrations of TPA in human serum from 10 male donors.
Serum from 10 apparently healthy male donors was measured in duplicate. The mean TPA concentration was determined to be 2,741 pg/mL with a range of 1,836- 4,012 pg/mL in male donors.

Product details
Tissue Plasminogen Activator (TPA) in vitro CatchPoint SimpleStep ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Tissue Plasminogen Activator (TPA) protein in human serum, plasma and cell culture supernatant.
This CatchPoint SimpleStep ELISA kit has been optimized for Molecular Devices Microplate Readers. Click here for a list of recommended Microplate Readers.
If using a Molecular Devices' plate reader supported by SoftMax® Pro software, a preconfigured protocol for these CatchPoint SimpleStep ELISA Kits is available with all the protocol and analysis settings at www.softmaxpro.org.
The CatchPoint SimpleStep ELISA employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. CatchPoint HRP Development Solution containing the Stoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRP generating a fluorescent product. Signal is generated proportionally to the amount of bound analyte and the intensity is measured in a fluorescence plater reader at 530/570/590 nm Excitation/Cutoff/Emission.
Tissue Plasminogen Activator (Tissue-type plasminogen activator or TPA) is a circulating serine protease involved in the breakdown of clots. TPA converts inactive plasminogen to active plasmin; in turn plasmin degrades the fibrin matrix in clots. In addition, plasmin can cleave TPA at Arg-310 with results in a two chain disulphide linked TPA that has even greater proteolytic activity. TPA is synthesized in many tissues and is secreted into most extracellular body fluids. Recombinant TPA is used medically to resolve or prevent blood clots in ischemic stroke or myocardial infarction.

Biological function summary
TPA 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.
Pathways
TPA 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.
