Description
Fibroblast growth factor-9, is an approximately 26 kDa secreted glycoprotein of the FGF family. Secreted human FGF-9 is a 205-207 aa protein that lacks the N-terminal 1-3 aa and shares 98% sequence identity with mouse, rat, equine, porcine and bovine FGF-9. FGF-9 is an autocrine/paracrine growth factor considered to be important for the growth and survival of motorneurons and prostate. Meanwhile, FGF9 is a potent mitogen and survival factor required for morphogenesis during embryonic development and numerous biological functions at adulthood.

Formulation
Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM Tris, 400 mM NaCl, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.
