Human Cytokine/Growth Factor/Chemokines Sample Spec sheets (subject to change without notice):


DATA SHEET:    recombinant Human Fibroblast Growth Factor-9

-Fibroblast Growth Factor-9 (FGF-9) , also known as 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. This recombinant human FGF-9 is a 23.4 kDa protein containing 207 amino acid residues.

Catalog#: RDI-1023

Supplied: sterile filtered and the the protein was lyophilized from 10mM Tris pH8.0 & 50mM NaCl( no additives)

Source: E. Coli

Purity: >95% by SDS-Page and HPLC analyses. Endotoxin level is less than 0.1ng per ug of FGF-9.

Reconstitution: The lyophilized FGF-9 should be reconstituted in 10mM TRIS pH8.0 to a concentration of 0.1-1.0mg/ml). Allow to set at least 30 minutes at 4 DEG C, tighten cap and rotate to reconstitute any material on sides of vial. If desired, you can centrifuge at 1000 rpm for 1 minute to concentrate volume in bottom of vial. This solution can be diluted into water or other buffered solutions or stored at -4 DEG C for up to 1 week or at -20 DEG C for future use.

Note:If this material is not to be used for coating or labeling(or other applications requiring carrier free material), the addition of 0.1% BSA to dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain concentration >10ug/ml.

Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored desiccated at -20 Deg C. Reconstituted human FGF-9 should be stored in working aliquots at -20 DEG C. AVOID FREQUENT FREEZE THAW CYCLES. EACh FREEZE THAW CYCLE WILL DIMINISH ACTIVITY.

Reactivity: The biological activity was determined by the does- dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors yielding an ED50 <0.5ng/ml, corresponding to a specific activity of >1 X 10 E06 (1 million) units/mg.
