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 alpha isoforms (3 Ig-like domains) and beta isoforms (2 Ig-like domains) of human FGF R2 in direct ELISAs and Western blots. In direct ELISAs, this antibody reacts with all isoforms of rhFGF R2 but shows approximately a 4-fold preference for (IIIc) isoforms. Approximately 100% cross-reactivity with recombinant mouse FGF R2, 15% cross-reactivity with recombinant human (rh) FGF RI ( beta isoforms), and no cross-reactivity with rhFGF RI ( alpha isoforms), rhFGF R3, or rhFGF R4 is observed.

Scientific Data Images for Human FGFR2 Antibody

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

Recombinant Human FGF R2a (IIIc) Fc Chimera (Catalog # 712-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 (IIIc) Fc Chimera (4 ng/mL) is neutralized (green line) by increasing concentrations of Human FGF R2 Monoclonal Antibody (Catalog # MAB684). The ND₅₀ is typically 1-5 µg/mL in the presence of heparin (10 µg/mL).

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.
