The urokinase plasminogen activator receptor (uPAR, encoded by PLAUR), also known as CD87, is a glycosylphosphatidylinositol (GPI)-anchored cell surface receptor that binds urokinase-type plasminogen activator (uPA) to regulate extracellular matrix degradation and tissue remodeling. By anchoring uPA, uPAR upregulates localized proteolytic activity through plasmin generation, facilitating cell migration, invasion, and intracellular signaling via interactions with integrins and growth factor receptors. Key pathways involving uPAR include the plasminogen activation cascade, MAPK/ERK, and PI3K/AKT signaling. Overexpression of uPAR is clinically linked to tumor metastasis, chronic inflammation, and fibrosis, with elevated levels observed in breast, lung, and colorectal cancers, as well as in atherosclerosis and kidney disease. Therapeutic strategies targeting uPAR include monoclonal antibodies (e.g., ATN-658), small-molecule inhibitors disrupting uPA-uPAR binding, and uPAR-directed CAR-T cells, several of which have shown antitumor efficacy in preclinical models. A phase I trial of the antibody-drug conjugate IMGN901 (anti-uPAR) demonstrated preliminary safety in solid tumors, highlighting its translational potential.

PLAUR Recombinant Monoclonal Antibody (CSB-RA018122MA1HU)
Validated Data
Immunofluorescence staining of hela cell with CSB-RA018122MA1HU at 1:30, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Mouse IgG(H+L).
Immunofluorescence staining of SH-SY5Y cell with CSB-RA018122MA1HU at 1:30, counter-stained with DAPI. The cells were fixed in 4% formaldehyde and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4C. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Mouse IgG(H+L).
Overlay Peak curve showing Hela cells surface stained with CSB-RA018122MA1HU (red line) at 1:100. Then 10% normal goat serum was Incubated to block non-specific protein-protein interactions followed by the antibody (1µg/1*106cells) for 45 min at 4°C. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1µg/1*106cells) used under the same conditions. Acquisition of >10,026 events was performed.
