Determined by a cell proliferation assay using Balb/c 3T3 cells. The expected ED50 is ≤ 10 ng/ml, corresponding to a specific activity of ≥ 1 x 105 units/mg.
Properties
PURITY:
≥ 95% by SDS-PAGE gel and HPLC analyses.
PHYSICAL STATE:
Lyophilized
STORAGE CONDITIONS:
The recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background and References
BACKGROUND:
FGF-9 is a heparin-binding growth factor that belongs to the FGF family. Proteins of this family play a central role during prenatal development, postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-9 targets glial cells, astrocytes cells and other cells that express FGFR 1c, 2c, 3b, 3c, and 4. Recombinant Human FGF-9 is a 23.2 kDa protein consisting of 206 amino acid residues.
