Principle of the Assay: Functionally active PAI-1 present in plasma reacts with urokinase coated and dried on a microtiter plate. Latent or complexed PAI-1 will not bind to the plate or be detected. Unbound PAI-1 samples are aspirated and an anti-PAI-1 primary antibody is added. Excess primary antibody is then aspirated. The bound antibody, which is proportional to the original active PAI-1 present in the samples, is then reacted with the horseradish peroxidase conjugated secondary antibody. Following an additional washing step, TMB substrate solution is then used for color development at 450nm. The amount of color development is directly proportional to the concentration of active PAI-1 in the sample.
Background: PAI-1 is involved in the regulation of the blood fibrinolytic system. Increased plasma levels of PAI-1 are implicated in the impairment of fibrinolytic function and may be associated with thrombotic diseases [1,2]. Levels of PAI-1 increase with age [5] and are elevated in conditions such as normal pregnancy [3] and sepsis [4].
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the serine proteinase inhibitor (serpin) superfamily. This member is the principal inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), and hence is an inhibitor of fibrinolysis. Defects in this gene are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1 deficiency), and high concentrations of the gene product are associated with thrombophilia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]
Uniprot Description
SERPINE1: a secreted protein that acts as 'bait' for tissue plasminogen activator, urokinase, and protein C. Its rapid interaction with TPA may function as a major control point in the regulation of fibrinolysis. Belongs to the serpin family. Interacts with VTN. Binds LRP1B; binding is followed by internalization and degradation. Plasma levels of PAI-1 and VCAM-1 together may be useful in predicting post-operative recurrence in patients with colorectal cancer.

Product Notes
The General SERPINE1 serpine1 (Catalog #AAA135492) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA135492 ELISA Kit recognizes General SERPINE1. It is sometimes possible for the material contained within the vial of "PAI-1 functional assay, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
