Human FGF-6 Antibody Summary

Species Reactivity

Human

Specificity

Detects human FGF‑6 in direct ELISAs and Western blots. In direct ELISAs and Western blots, less than 17% cross-reactivity with recombinant human (rh) FGF-4 is observed and less then 1% cross-reactivity with rhFGF acidic, rhFGF basic, and rhFGF-5 is observed. Neutralizes the biological activity of rhFGF-6, but will not neutralize the biological activity of rhFGF acidic, rhFGF basic, rhFGF-4, or rhFGF-5.

Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Human FGF‑6 (Catalog # 238-F6)

Neutralization

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 15-25 µg/mL in the presence of 1 ng/mL Recombinant Human FGF‑6.

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 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 Polyclonal Antibody (Catalog # AB-238-NA). The ND₅₀ is typically 15-25 µg/mL.

Background: FGF-6

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).
