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

Specificity

Detects all isoforms of human FGF R2 ( alpha and beta, IIIb and IIIc). In direct ELISAs, approximately 25‑50% cross-reactivity with mouse FGF R2 and no cross-reactivity with any isoform of recombinant human (rh) FGF R1, rhFGF R3, or rhFGF R4 is observed.

Scientific Data Images for Human FGFR2 Antibody

FGF R2 in Human Adenocarcinoma.

FGF R2 was detected in immersion fixed paraffin-embedded sections of human adenocarcinoma using Mouse Anti-Human FGF R2 Monoclonal Antibody (Catalog # MAB6843) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

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

Recombinant Human FGF R2 beta (IIIc) Fc Chimera (Catalog # 684-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 R2 beta (IIIc) Fc Chimera (6 ng/mL) is neutralized (green line) by increasing concentrations of Human FGF R2 Monoclonal Antibody (Catalog # MAB6843). The ND₅₀ is typically 0.1-0.5 µg/mL in the presence of heparin (10 µg/mL).

Applications for Human FGFR2 Antibody

Application

Recommended Usage

CyTOF-ready

Flow Cytometry

2.5 µg/10⁶ cells
Sample: Kato III human cell line

Immunohistochemistry

8-25 µg/mL

Neutralization

Measured by its ability to neutralize FGF R2 beta-mediated inhibition of proliferation in the NR6R-3T3 mouse fibroblast cell line. The Neutralization Dose (ND₅₀) is typically 0.1-0.5 µg/mL in the presence of 6 ng/mL Recombinant Human FGF R2 beta (IIIc) Fc Chimera, 0.3 ng/mL Recombinant Human FGF acidic, and 10 µg/mL heparin.

Background: FGFR2

Fibroblast Growth Factor Receptor 2 (FGF R2) is one of four closely related transmembrane tyrosine kinases (FGF R1‑4) that function as receptors for the fibroblast growth factor family. Multiple isoforms are generated by alternative mRNA splicing resulting in extracellular domains with three ( alpha isoforms) or two ( beta isoforms) Ig-like domains. In addition, alternative exon usage in the Ig III (membrane proximal) domain results in IIIb or IIIc isoforms.
