Detects mouse FGF R4 in Western blots. In Western blots, approximately 35% cross‑reactivity with recombinant human (rh) FGF R4 is observed and less than 5% cross-reactivity with rhFGF R1 alpha (IIIb), rhFGF R1 alpha (IIIc), rhFGF R1 beta (IIIb), rhFGF R1 beta (IIIc), recombinant mouse (rm) FGF R2 alpha (IIIb), rmFGF R2 alpha (IIIc), rmFGF R2 beta (IIIb), rmFGF R2 beta (IIIc), rmFGF R5, and rmFGF R5 beta is observed.
FGF R4 in Mouse Embryo. FGF R4 was detected in immersion fixed frozen sections of mouse embryo (E11.5) using Goat Anti-Mouse FGF R4 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF2265) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to the epidermis.

Background: FGF R4
FGF R4 is a transmembrane receptor tyrosine kinase that binds several ligands of the FGF family. It is expressed in the early embryo, and its expression has been suggested to play an important role in the formation of mesoderm and posterior structure (1). Recent studies also indicated that FGF R4 may be used as a marker to distinguish neural stem cells from other precursor cells (2). The extracellular domain of mouse FGF R4 shares 95% and 89% amino acid sequence homology with its rat and human homologs, respectively.
