表达区间及表达系统（Source）
Human PLAU, His Tag (PLU-H5229) is expressed from human 293 cells (HEK293). It contains AA Ser 21 - Leu 431 (Accession # NP_002649.1).
Predicted N-terminus: Ser 21
Request for sequence
蛋白结构（Molecular Characterization）
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.
Please note that the protein is not activated by protease digestion. In vitro activation is generally recommended for higher activity.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>92% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM Sodium Acetate, 100 mM NaCl, pH5.0 with trehalose as protectant.

背景
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).
