Human PLAU / uPA Protein, His Tag

Urokinase - type plasminogen activator is also known as PLAU and UPA, a serine protease with an extremely limited substrate specificity, cleaving the sequence Cys – Pro – Gly - Arg560 - Val561 – Val – Gly – Gly – Cys in plasminogen to form plasmin. uPA is a potent marker of invasion and metastasis in a variety of human cancers associated with breast, stomach, colon, bladder, ovary, brain and endometrium.uPA and its receptor (uPAR) have been implicated in a broad spectrum of pathophysiological processes, including fibrinolysis, proteolysis, inflammation, atherogenesis and plaque destabilization, all of which are involved in the pathogenesis of MI (myocardial infarction) .

Human PLAU, His Tag is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 47.2 kDa. The protein migrates as 45-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.<br> <strong>Please note that the protein is not activated by protease digestion. In vitro activation is generally recommended for higher activity.</strong>

● -20°C to -70°C for 12 months in lyophilized state; ● -70°C for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Immobilized Human PLAU, His Tag (Cat. No. PLU-H5229) at 5 μg/mL (100 μL/well) can bind Biotinylated Human uPAR, His,Avitag (Cat. No. UPR-H82E7) with a linear range of 0.3-5 ng/mL (QC tested).
