Plasminogen activator inhibitor-1 is the principal inhibitor of tissue plasminogen activator(tPA) and uPA, the activators of plasminogenand hence fibrinolysis(the physiological breakdown of blood clots). It is a serine protease inhibitor(serpin) protein (SERPINE1). The other PAI, plasminogen activator inhibitor-2(PAI-2) is secreted by the placentaand only present in significant amounts during pregnancy. In addition, protease nexinacts as an inhibitor of tPA. SERPINE1, however, is the main inhibitor of the plasminogen activators.
SERPINE1 Human Recombinant fused to an N-terminal His-Tag produced in E.Coli is a single, non-glycosylated polypeptide chain containing 400 amino acids (24-402) and having a molecular mass of 45kDa.
SERPINE1 is fused to a 21 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
50mM NaAc (pH 5.5), 10% glycerol and 0.1M NaCl.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
The IC50 for this effect is less than 3nM, measured by its ability to inhibit uPA cleavage of the substrate Z-GGRAMC.
