Fibroblast Growth Factor-9 (FGF-9, Glial Activating Factor) is a heparin binding growth factor that stimulates the proliferation and activation of glial cells and other cells that express FGF receptors. Murine FGF-9 is a 23.3kD protein containing 205 aa residues.

Biological Activity:
USBio's murine FGF-9 is fully biologically active when compared to standards. The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors is  0.5ng/ml, Corresponding to a specific activity of 2 x 10e6u/mg.

Concentration Range for most in vitro applications: 0.1-1ng/ml

Responding Cells (partial list): Murine FGF-9 exerts full activity on both murine and human cells (i.e. Glial cells, 3T3 fibroblasts).

Storage and Stability: Lyophilized powder may be stored at RT or desiccated at 4°C for short-term only. Reconstitute to nominal volume by adding sterile 40mM Tris, pH 8.0, aliquot and store at -20°C. Reconstituted product is stable for 12 months at
-20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
23.3kD
Source: E. coli

Purity: 95% by SDS-PAGE and HPLC analyses.

Endotoxin: 0.1ng/ug.

Form: Supplied as a lyophilized powder from 20mM Tris, pH 8.0, 75mM sodium chloride.

Concentration: 1mg/ml

Reconstitution: To obtain a 2 mg/ml solution, add 0.5 µl of water per µg of protein. Dilution into solutions of lower ionic strength should be done immediately before use. For most in vitro applications, FGF-9 exerts its biological activity in the concentration range of 0.1 to 20.0 ng/ml.
