Lys23-Asn502
Accession # Q8BVA0
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

Mouse Osteoactivin/GPNMB Sandwich Immunoassay

Recommended Concentration
Reagent
ELISA Capture (Matched Antibody Pair)
0.2-0.8 µg/mL 

Use in combination with:

Detection Reagent: Mouse Osteoactivin/GPNMB Biotinylated Antibody (Catalog # BAF2330)

Standard: Recombinant Mouse Osteoactivin/GPNMB Fc Chimera Protein, CF (Catalog # 2330-AC)

Neutralization
Measured by its ability to neutralize Osteoactivin/GPNMB-mediated adhesion of the SVEC4‑10 mouse vascular endothelial cell line. The Neutralization Dose (ND50) is typically 0.2-0.8 µg/mL in the presence of 0.25 µg/mL Recombinant Mouse Osteoactivin/GPNMB Fc Chimera.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Cell Adhesion Mediated by Osteoactivin/GPNMB and Neutralization by Mouse Osteoactivin/GPNMB Antibody. Recombinant Mouse Osteoactivin/GPNMB Fc Chimera (Catalog # 2330-AC), immobilized onto a microplate previously coated with Goat Anti-Mouse IgG Fc (Catalog # G-202-C), supports the adhesion of the SVEC4‑10 mouse vascular endothelial cell line in a dose-dependent manner (orange line), as measured by endogenous cellular lysosomal acid phosphatase activity. Adhesion elicited by Recombinant Mouse Osteoactivin/GPNMB Fc Chimera (0.25 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse Osteoactivin/
GPNMB Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2330). The ND50 is typically
0.2‑0.8 µg/mL.

Background: Osteoactivin/GPNMB

Osteoactivin (also named GPNMB and DC-HIL) is a 125 kDa, intracellular glycoprotein that is associated with cell endosomal/lysosomal compartments (1, 2). Mouse osteoactivin is synthesized as a type I, transmembrane, 574 amino acid (aa) precursor that contains a 22 aa signal sequence, a 478 aa luminal/extracellular domain, a 23 aa transmembrane segment and a 51 aa cytoplasmic tail. The luminal region contains an N-terminal heparin-binding motif, multiple glycosylation sites, an RGD motif and a 130 aa PKD domain. The intracellular tail also has an RGD motif, plus an ITAM (Y-x-x-I) and lysosomal targeting (L-L) motif. The extracellular/luminal region is 89% and 74% aa identical to the equivalent regions in rat and human, respectively. Cells known to express osteoactivin include osteoblasts, dendritic cells, and melanocytes, plus fetal chondrocytes and stratum basale keratinocytes (2, 3). Osteoactivin is reported to bind to heparan sulfate-proteoglycan, possibly on the surface of fibroblasts and endothelial cells (2). It may also interact with integrins.
