Mouse FGF‑8b Isoform Antibody Summary

Species Reactivity
Mouse
Specificity
Detects mouse FGF‑8b Isoform in direct ELISAs and Western blots. In direct ELISAs and Western blots, less than 1% cross-reactivity with recombinant human (rh) FGF acidic, rhFGF basic, rhFGF-4, rhFGF-5, rhFGF-6, rhFGF-7 and rhFGF-9 is observed. It does, however,
cross‑react with recombinant mouse FGF-8c in neutralizing bioassay.

Neutralization
Measured by its ability to neutralize FGF‑8-induced proliferation in the NR6R‑3T3 mouse fibroblast cell line. Rizzino, A. et al. (1988) Cancer Res. 48:4266. The Neutralization Dose (ND50) is typically 0.4-2.4 µg/mL in the presence of 60 ng/mL Recombinant Mouse FGF‑8b Isoform and 1 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.

Cell Proliferation Induced by FGF‑8 and Neutralization by Mouse FGF‑8 Antibody. Recombinant Mouse FGF-8b Isoform (Catalog # 423-F8) stimulates proliferation in the the NR6R-3T3 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Mouse FGF-8b Isoform (60 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse FGF-8b Isoform Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-423-NA). The ND50 is typically 0.4-2.4 µg/mL in the presence of heparin (1 µg/mL).

FGF‑8 in Human Prostate. FGF-8 was detected in immersion fixed paraffin-embedded sections of human prostate using Goat Anti-Mouse FGF-8 b Isoform Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-423-NA) 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 epithelial and endothelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: FGF-8

FGF-8 is a member of the fibroblast growth factor family that was originally discovered as a growth factor essential for the androgen-dependent growth of mouse mammary carcinoma cells (1‑3). Alternate splicing of mouse FGF-8 mRNA generates eight secreted isoforms, designated a‑h, but only FGF-8a, b, e and f exist in humans (4). FGF-8 contains a 22 amino acid (aa) signal sequence, an N‑terminal domain that varies according to the isoform (30 aa for FGF-8b; 20 aa for the shortest, FGF-8a), a 125 aa FGF domain and a 37 aa proline‑rich C‑terminal sequence. The FGF domain of FGF-8 shares the most aa identity with FGF17 (75%) and FGF-18 (67%), and the three form an FGF subfamily (2). Mouse FGF-8b shares 100% aa identity with human FGF-8b. FGF-8 is widely expressed during embryogenesis, and mediates epithelial-mesenchymal transitions. It plays an organizing and inducing role during gastrulation, and regulates patterning of the midbrain/hindbrain, eye, ear, limbs and heart in the embryo (2, 5‑8). The isoforms may play different roles in development. FGF-8b shows the strongest receptor affinity and oncogenic transforming capacity although FGF-8a and FGF-8e are also transforming and have been found in human prostate, breast or ovarian tumors (1, 5, 9‑12). FGF-8 shows limited expression in the normal adult, but low levels are found in the reproductive and genitourinary tract, peripheral leukocytes and bone marrow hematopoietic cells (3, 9, 13).
