The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Biological activityBiological Activity:
The ED50, calculated by the dose-dependant proliferation of BAF3 cells expressing FGF receptors (measured by 3H-thymidine uptake) is <0.5 ng/ml, corresponding to a specific activity of 2 x 106 Units/mg.
% SDS-PAGE. ab73212 is purified by proprietary chromatographic techniques. Purity is greater than 95.0% as determined by RP-HPLC and SDS-PAGE.
Additional notesFor long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

This product is an active protein and may elicit a biological response in vivo, handle with caution.
ReconstitutionReconstitute in sterile 18MOhm-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Fibroblast growth factor 9
Glia Activating Factor
Heparin-binding growth factor 9
FunctionMay have a role in glial cell growth and differentiation during development, gliosis during repair and regeneration of brain tissue after damage, differentiation and survival of neuronal cells, and growth stimulation of glial tumors.
Tissue specificityGlial cells.
Involvement in diseaseDefects in FGF9 are the cause of multiple synostoses syndrome type 3 (SYNS3) [MIM:612961]. Multiple synostoses syndrome is an autosomal dominant condition characterized by progressive joint fusions of the fingers, wrists, ankles and cervical spine, characteristic facies and progressive conductive deafness.
Sequence similaritiesBelongs to the heparin-binding growth factors family.
Post-translational modificationsThree molecular species were found (30 kDa, 29 kDa and 25 kDa), cleaved at Leu-4, Val-13 and Ser-34 respectively. The smaller ones might be products of proteolytic digestion. Furthermore, there may be a functional signal sequence in the 30 kDa species which is uncleavable in the secretion step. N-glycosylated.
