The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
ab170082 is >60 percent active as determined by SDS PAGE.
>95% by SDS-PAGE . The His tag allows for the immobilization of functionally active PAI1 onto surfaces such as metal chelate microtiter plates or Ni+2 resins. The purification conditions are gentle and result in an active fraction >99 percent pure and >60 percent active as determined by SDS PAGE.

Endothelial plasminogen activator inhibitor
Plasminogen activator inhibitor 1
Plasminogen activator inhibitor type 1
Serine (or cysteine) proteinase inhibitor
Serine (or cysteine) proteinase inhibitor clade E (nexin plasminogen activator inhibitor type 1) member 1
Serpin peptidase inhibitor clade E
Serpin peptidase inhibitor clade E (nexin plasminogen activator inhibitor type 1) member 1
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.
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.
Belongs to the serpin family.
Inactivated by proteolytic attack of the urokinase-type (u-PA) and the tissue-type (TPA), cleaving the 369-Arg- -Met-370 bond.
