ED50 < 5.0 ng/mL, measured by a cell proliferation assay using 3T3 cells in the presence of 1 μg/mL of heparin, corresponding to a specific activity of > 2.0x 10^5 units/mg. AA 23-215, expressed with an N-terminal Met.
Lyophilized recombinant human Fibroblast Growth Factor-8 (rhFGF-8) remains stable up to 6 months at -80 °C from date of receipt. Upon reconstitution, rhFGF-8 should be stable up to 2 weeks at 4 °C or up to 3 months at -20 °C.
Fibroblast Growth Factor-8 (FGF-8) is a heparin-binding growth factor of the FGF family. There are 4 known forms of FGF8 produced by alternative splicing: FGF8a, FGF-8b, FGF-8e and FGF-8f. The human and mouse FGF8b are identical of aa sequences. FGF-8 plays an important role in the regulation of embryonic development, cell proliferation, cell differentiation and cell migration. FGF-8 is required for normal brain, eye, ear and limb development during embryogenesis. It is also required for normal development of the gonadotropin- releasing hormone (GnRH) neuronal system.Recombinant human Fibroblast Growth Factor-8 (rhFGF-8) produced in E. coli is a single non-glycosylated polypeptide chain containing 194 amino acids. A fully biologically active molecule, rhFGF-8 has a molecular mass of 22.5 kDa analyzed by reducing SDS-PAGE. Synonyms: FGF-8b, AIGF, HBGF
