Measured by its ability to neutralize FGF R3-mediated inhibition of proliferation in the NR6R‑3T3 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 3-12 µg/mL in the presence of 12 ng/mL Recombinant Mouse FGF R3 (IIIc) Fc Chimera, 0.3 ng/mL Recombinant Human FGF acidic, and 10 µg/mL heparin.
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.
FGF R3 Inhibition of FGF acidic-dependent Cell Proliferation and Neutralization by Mouse FGF R3 Antibody. Recombinant Mouse FGF R3 (IIIc) Fc Chimera (Catalog # 710-MF) inhibits Recombinant Human FGF acidic (Catalog # 232‑FA) induced proliferation in the NR6R‑3T3 mouse fibroblast cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Human FGF acidic (0.3 ng/mL) activity elicited by Recombinant Mouse FGF R3 (IIIc) Fc Chimera (12 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse FGF R3 Monoclonal Antibody (Catalog # MAB710). The ND50 is typically 3-12 µg/mL in the presence of heparin (10 µg/mL).

Background: FGF R3
Fibroblast growth factors (FGFs) comprise a family of at least eighteen structurally related proteins that are involved in a multitude of physiological and pathological cellular processes, including cell growth, differentiation, angiogenesis, wound healing and tumorgenesis. The biological activities of the FGFs are mediated by a family of type I transmembrane tyrosine kinases which undergo dimerization and autophosphorylation after ligand binding. Four distinct genes encoding closely related FGF receptors, FGF R1‑4, are known. All four genes for FGF Rs encode proteins with an N‑terminal signal peptide, three immunoglobulin (Ig)‑like domains, an acid‑box region containing a run of acidic residues between the IgI and IgII domains, a transmembrane domain and the split tyrosine‑kinase domain. Multiple forms of FGF R1‑3 are generated by alternative splicing of the mRNAs. A frequent splicing event involving FGF R1 and 2 results in receptors containing all three Ig domains, referred to as the alpha isoform, or only IgII and IgIII, referred to as the beta isoform. Only the alpha isoform has been identified for FGF R3 and FGF R4. Additional splicing events for FGF R1‑3, involving the C‑terminal half of the IgIII domain encoded by two mutually exclusive alternative exons, generate FGF receptors with alternative IgIII domains (IIIb and IIIc). A IIIa isoform which is a secreted FGF binding protein containing only the N‑terminal half of the IgIII domain plus some intron sequences has also been reported for FGF R1. Mutations in FGF R1‑3 have been found in patients with birth defects involving craniosynostosis. The complex patterns of expression of these receptors as well as the specificity of their interactions with the various FGF ligand family members are being investigated.
