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.

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).
