Product overview
Abcam’s PAI1 (SERPINE1) in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of active PAI1 (SERPINE1) in rat plasma and serum.
Functionally active PAI1 present in plasma reacts with urokinase coated and dried on a microtiter plate. Latent or complexed PAI1 will not bind to the plate and will not be detected. Unbound PAI1 samples are washed away and an anti-PAI1 primary antibody is added. Excess primary antibody is washed away and bound antibody, which is proportional to the original active PAI1 present in the samples, is then bound by the horseradish peroxidase secondary antibody. Following an additional washing step, TMB is then used for color development at 450nm. The amount of color development is directly proportional to the concentration of active PAI1 in the sample.

Function
This inhibitor 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. -
Tissue specificity
Found in plasma and platelets and in endothelial, hepatoma and fibrosarcoma cells. -
Involvement in disease
Defects in SERPINE1 are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1D) [MIM:613329]. It is a hematologic disorder characterized by increased bleeding after trauma, injury, or surgery. Affected females have menorrhagia. The bleeding defect is due to increased fibrinolysis of fibrin blood clots due to deficiency of plasminogen activator inhibitor-1, which inhibits tissue and urinary activators of plasminogen.
Note=High concentrations of SERPINE1 seem to contribute to the development of venous but not arterial occlusions. -
Sequence similarities
Belongs to the serpin family. -
Post-translational
modificationsInactivated by proteolytic attack of the urokinase-type (u-PA) and the tissue-type (TPA), cleaving the 369-Arg-
-Met-370 bond. -
