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.

Purity >97% by SDS-PAGE and HPLC analyses. Biological Activity The ED50 as determined by a cell proliferation assay using monkey 4MBr-5 cells is less than 120 ng/mL, corresponding to a specific activity of > 8.3 × 103 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 20 mM Tris, 500 mM NaCl, pH 7.4, 5% trehalose. 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. Shipping and Storage The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Cautions 1. Avoid repeated freeze-thaw cycles. 2. For your safety and health, please wear lab coats and disposable gloves for operation. 3. For research use only!
