Human uPAR, His Tag (UPR-H5226) is expressed from human 293 cells (HEK293). It contains AA Leu 23 - Arg 303 (Accession # AAH02788).
Predicted N-terminus: Leu 23
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 32.3 kDa. The protein migrates as 40-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>92% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human uPAR, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 92%.
Measured by its inhibitory ability in a competitive ELISA.
Serial dilutions of Human uPAR, His Tag (Cat. No. UPR-H5226) were added into Human PLAU, His Tag (Cat. No. PLU-H5229) : Biotinylated Human uPAR, His,Avitag (Cat. No. UPR-H82E7) binding reactions. The half maximal inhibitory concentration (IC50) is 2.96 μg/mL (QC tested).
Urokinase plasminogen activator surface receptor (U-PAR) is also known as PLAUR, Monocyte activation antigen Mo3, CD antigen CD87. PLAUR contains three UPAR/Ly6 domains. U-PAR is expressed in neurons of the rolandic area of the brain (at protein level) and is also expressed in the brain. PLAUR / CD87 interacts with MRC2, SRPX2 and SORL1. PLAUR / UPAR acts as a receptor for urokinase plasminogen activator and plays a role in localizing and promoting plasmin formation. U-PAR mediates the proteolysis-independent signal transduction activation effects of U-PA.
