General description

ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Clone 2G10 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects human Urokinase plasminogen activator surface receptor (uPAR).


A recombinant fragment corresponding the first 277 amino acids from human Urokinase plasminogen activator surface receptor (uPAR).


Anti-uPAR, clone 2G10 ZooMAb, Cat. No. ZRB1224, is a Rabbit monoclonal antibody that targets uPAR and has been tested for use in Flow Cytometry, Immunocytochemistry, Immunohistochemistry, Inhibition Assay, and Western Blotting.

Inhibits Activity/Function: A representative lot of this antibody inhibited the invasion of MDA-MB-231 cells (Harel, E., et al., 2014 UCSF Scientific Poster).

Flow Cytometry Analysis: 0.1 μg from a representative lot detected uPAR in one million SH-SY5Y cells.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected uPAR in human lung cancer tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected uPAR in HT1080 cells.

Note: Actual optimal working dilutions must be determined by the end user as specimens and experimental conditions may vary.

Target description

Urokinase plasminogen activator surface receptor (UniProt: Q03405; also known as U-PAR, uPAR. Monocyte activation antigen Mo3, CD87) is encoded by the PLAUR (also known as MO3, UPAR) gene (Gene ID: 5329) in human. uPAR is a GPI-anchored cell membrane receptor for urokinase plasminogen activator (uPA), an enzyme responsible for the activation of plasmin and degradation of extracellular matrix components. It is also a subject to negative-feedback regulation by U-PA, which cleaves it into an inactive form. uPAR is synthesized with a signal peptide (aa 1-22) and a propeptide (aa 306-335), which are subsequently cleaved off to produce the mature form. The mature form has three homologous domains known as DI, DII, and DIII. Higher expression of uPAR has been reported in many human cancers, including non-small cell lung cancer and colorectal cancer and it correlates with a poor prognosis and early invasion and metastasis. uPAR, through integrins interaction, is reported to play a crucial role in activating Src, FAK and paxillin, which are considered as critical mediators of cell migration. In addition, via its interaction with chemotaxis receptors for fMet-lleu-Phe, it mediates both uPA and fMLF-dependent cell migration. uPAR has also been implicated in cross-talk with EGFR, which mediates the shift from tumor cell dormancy to proliferation. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
