ED50 < 10 ng/mL, measured by a cell proliferation assay using 3T3 Cells, corresponding to a specific activity of > 1.0x 105 units/mg. AA 27 -199, expressed with an N-terminal Met.
Lyophilized recombinant human Fibroblast Growth Factor-18 (rhFGF-18) remains stable up to 6 months at -80 °C from date of receipt. Upon reconstitution, rhFGF-18 should be stable up to 2 weeks at 4 °C or up to 3 months at -20 °C.
Fibroblast Growth Factor-18 (FGF-18) is a heparin-binding growth factor that is a member of the FGF family. FGF-18 signals through FGFR 1c, 2c, 3c, and 4. FGF-18 plays an important role in the regulation of cell proliferation, cell differentiation and cell migration. FGF-18 is required for normal ossification and bone development. It can also stimulate hepatic and intestinal proliferation.Recombinant human Fibroblast Growth Factor-18 (rhFGF-18) produced in E. coli is a single non-glycosylated polypeptide chain containing 174 amino acids. A fully biologically active molecule, rhFGF-18 has a molecular mass of 20.3 kDa analyzed by reducing SDS-PAGE. Synonyms: Fibroblast Growth Factor-18, zFGF5, FGFI
