Detects human FGF-6 in direct ELISAs and Western blots. In Western blots, approximately 50% cross-reactivity with recombinant human (rh) FGF-4 is observed, less than 5% cross-reactivity with rhFGF-9 is observed, and less than 2% cross-reactivity with FGF-acidic, rhFGF-5, and rhFGF-7 is observed. In direct ELISAs, less than 1% cross-reactivity with rh beta -ECGF, recombinant mouse (rm) FGF-8b, and rmFGF-8c is observed.
Polyclonal Goat IgG
E. coli-derived recombinant human FGF-6 Gly41-Ile208 Accession # P10767
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize FGF‑6-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 0.2-1 µg/mL in the presence of 1 ng/mL Recombinant Human FGF‑6 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‑6 and Neutralization by Human FGF‑6 Antibody. Recombinant Human FGF‑6 (Catalog # 238-F6) stimulates proliferation in the the NR6R‑3T3 mouse fibroblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human FGF‑6 (1 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human FGF‑6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF238). The ND50 is typically 0.2-1 µg/mL in the presence of heparin (1 µg/mL).

Fibroblast Growth Factor-6 (FGF-6), also known as HST-2, is a 25-28 kDa member of the FGF family of heparin binding polypeptides which are potent regulators of cell proliferation, differentiation, and function. FGF proteins contain a 120 amino acid (aa) core FGF domain that exhibits a beta -trefoil structure (1, 2). Mature human FGF-6 is a 171 aa protein that shares 94% aa sequence identity with mouse and rat FGF-6 (3). It binds and signals primarily through FGF R1c, 2c, and 4 (4). FGF-6 functions as a mitogen for fibroblasts, vascular endothelial cells, and prostate carcinoma cells, and N-linked glycosylation is required for the full mitogenic effect (5‑7). FGF-6 expression is restricted to skeletal muscle during development although it can be upregulated in prostate cancer and Kaposi sarcoma (7-9). In the adult, FGF-6 is upregulated in injured skeletal muscle and is required for muscle regeneration (10). FGF-6 inhibits the terminal differentiation of myoblasts and also cooperates with TGF-beta 2 to promote chondrogenesis in embryonic somites (8, 11).
