Technical Data
Plasminogen Activator Inhibitor Type 1, inhibitory (PAI-1)
Plasminogen Activator Inhibitor 1 (PAI-1) is a glycoprotein found in plasma that is implicated in the processes of angoigenisis, hemostasis, tumor metastasis, fibrionlysis, ovulation, embryonic development and inflammation. The elevation of PAI-1 has shown to correlate with the prognosis of many cancers including breast cancer. PAI-1 is activated by the glycoprotein vitronectin. Vitronectin binds to PAI-1 and modulates fibrinolysis and cell migration. This binding has proven to be an important inhibitor of the activated form of protein C (APC).

Suitable for use in Western Blot, Immunohistochemistry and ELISA. Other applilcations have not been tested.

Recommended Dilutions:

Recombinant human PAI-1.
Purified by Protein A affinity chromatography.
Supplied in liquid in PBS, pH 7.4.
Recognizes human PAI-1 and exhibits inhibitory characteristics. Binds to an epitope localized to the F-Helix of PAI-1. The PAI-1/mab complex acts as a substrate for its target proteinases tPA and uPA. Species Crossreactivity: mouse.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
