Anti-uPAR Antibody, clone 3C6 (Azide Free)

UPAR protein or CD87 acts as the receptor for urokinase plasminogen activator (uPA), or urokinase, an important enzyme commonly found in the blood and extracellular matrix fluids. UPA is the enzyme that is responsible for the activation of plasmin, a powerful serine proteinase necessary for clotting, wound healing, and extracellular matrix degradation and remodeling. Urokinase also has major roles in vascular disease and cancer growth and spreading. UPAR, the receptor, is also important in cancer biology as it is through this receptor that the uPA effects are mediated, and these effects play a role in cell adhesion, migration and cell proliferation of cancers. UPAR also binds vitronectin and uPAR associated proteins (uPARAP) as well as several members of the integrin family of proteins. UPAR’s primary physiological role is as part of the uPA activation system which is involved in tissue reorganization and wound healing. By binding urokinase it restricts the activation of plasminogen to plasmin to the immediate vicinity of the cell membrane and thus helps to regulate and limit the strength and duration of the remodeling process.

This antibody competes with beta 1 integrins for uPAR binding and inhibits uPAR-mediated cell invasion. Inhibition of uPAR is maximized with the combination of Anti-uPAR, clone 3C6 (Cat. # MABC89) and Anti-uPAR, clone 2G10 (Cat. # MABC88).

Linear peptide corresponding to Human uPAR.

This Anti-uPAR Antibody, clone 3C6 (Azide Free) is validated for use in Western Blotting and Flow Cytometry and Inhibits Activity/Function for the detection of uPAR.

Western Blot Analysis: A representative lot of this antibody detected non-reduced uPAR recombinant protein (see Harel, E., et al., 2014 UCSF Scientific Poster).

Flow Cytometry Analysis: A representative lot of this antibody detected uPAR in MDA-MB-231, H1299 and PC3 cells (see Harel, E., et al., 2014 UCSF Scientific Poster).

Flow Cytometry Analysis: A representative lot of this antibody detected uPAR in HEK293 cells stably expressing uPAR (Dureseti et al., (2010) JBC. 285(35):26878–26888).

Inhibition Assay: A representative lot of this antibody inhibted the invasion of MDA-MB-231 cells (see Harel, E., et al., 2014 UCSF Scientific Poster). Inhibition of uPAR is maximized with the combination of Anti-uPAR, clone 3C6 (Cat. # MABC89) and Anti-uPAR, clone 2G10 (Cat. # MABC88).

Inhibition Assay: A representative lot of this antibody blocked uPAR-mediated invasion and signaling in H1299 cells (Dureseti et al., (2010) JBC. 285(35):26878–26888). Inhibition of uPAR is maximized with the combination of Anti-uPAR, clone 3C6 (Cat. # MABC89) and Anti-uPAR, clone 2G10 (Cat. # MABC88).

Evaluated by Western Blotting in reduced and non-reduced human uPAR recombinant protein.

Western Blotting Analysis: A 1:2500 dilution of this antibody detected uPAR in 1 µg of non-reduced human uPAR recombinant protein, but not in 1 µg of reduced human uPAR recombinant protein.

~45 kDa observed.
Recombinant human uPAR (Leu23-Arg303) has a predicted molecular weight of ~31 kDa, but runs around ~45 kDa under non-reduced conditions.
