Description
Mature human FGF-10 is an approximately 20 kDa protein that contains a serine-rich region near its N-terminus (2, 3). It shares 93% and 96% amino acid sequence identity with mouse and rat FGF-10, respectively. Mature human FGF-10 is an approximately 20 kDa protein that contains a serine-rich region near its N-terminus (2, 3). It shares 93% and 96% amino acid sequence identity with mouse and rat FGF-10, respectively. FGF-10 is a stromal-derived paracrine growth factor considered to be important during embryogenesis. FGF-10 plays an important role in adipogenesis, at least partly by contributing to the expression of C/EBPβ through an autocrine/paracrine mechanism. During cardiogenesis, FGF-10 is expressed in the anterior second heart field. Together with Fibroblast growth factor 8 (FGF-8), FGF10 promotes the proliferation of these cardiac progenitor cells that form the arterial pole of the heart.

Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Purity
>95% by SDS-PAGE and HPLC analyses.
Biological Activity
The ED50 as determined by thymidine uptake assay using FGF-receptors transfected BaF3 cells is less than 0.5 ng/mL, corresponding to a specific activity of > 2.0 × 106 IU/mg. Fully biologically active when compared to standard.
Endotoxin
< 1.0 EU per 1μg of the protein by the LAL method.
Formulation
Lyophilized from a 0.2 μm filtered concentrated solution in 2 × PBS, 600 mM NaCl, pH 7.4, 1 mM mercaptoethanol.
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.
