Product Specifications

Immunogen

Mouse myeloma cell line NS0-derived recombinant human FGF R2 isoforms and S. frugiperda insect ovarian cell line Sf 21-derived recombinant human FGF R2 isoforms

Specificity

Reacts with multiple isoforms of human FGF R2 although it shows a marked preference for human FGF R2 (IIIb) isoforms in some assays as described below. In direct ELISAs, displays a three-fold preference for FGF R2 (IIIb) isoforms over (IIIc) isoforms. Shows approximately 50% cross-reactivity with recombinant mouse (rm) FGF R2 isoforms and no cross-reactivity with any isoforms of recombinant human (rh) FGF R1 or rhFGF R3. In Western blots, shows approximately 25% cross-reactivity with rhFGF R2 (IIIc) isoforms, 100% cross-reactivity with all isoforms of rmFGF R2 and no cross-reactivity with any isoforms of rhFGF RI, rhFGF R3, or rhFGF R4. Neutralizes the bioactivity of rhFGF R2 (IIIb) isoforms.

Scientific Data Images for Human FGFR2 (IIIb) Antibody

FGF R2 alpha Inhibition of FGF acidic-dependent Cell Proliferation and Neutralization by Human FGF R2 Antibody.

FGF R2 alpha Inhibition of FGF acidic-dependent Cell Proliferation and Neutralization by Human FGF R2 Antibody.

Recombinant Human FGF R2a (IIIb) Fc Chimera (Catalog # 663-FR) 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 Human FGF R2a (IIIb) Fc Chimera (6 ng/mL) is neutralized (green line) by increasing concentrations of Human FGF R2 (IIIb) Monoclonal Antibody (Catalog # MAB665). The ND50 is typically 2-8 µg/mL in the presence of heparin (10 µg/mL).

Applications for Human FGFR2 (IIIb) Antibody

Application
Recommended Usage

Western Blot

1 µg/mL
Sample: Recombinant Human FGF R2 beta (IIIb) Fc Chimera (Catalog # 665-FR)

Neutralization

Measured by its ability to neutralize FGF R2 alpha-mediated inhibition of proliferation in the NR6R-3T3 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 2-8 µg/mL in the presence of 6 ng/mL Recombinant Human FGF R2 alpha (IIIb) Fc Chimera, 0.3 ng/mL Recombinant Human FGF acidic, and 10 µg/mL heparin.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: FGFR2

FGF R2 is a transmembrane tyrosine kinase that functions as a receptor for several FGF family proteins. The extracellular domain includes three ( alpha isoforms) or two ( beta isoforms) Ig-like domains. Alternative exon usage results in IIIb or IIIc isoforms that differ in their membrane proximal Ig-like domain.
