Scientific Background
Fibroblast Growth Factor-10 (FGF-10) is a mitogen mainly produced by mesenchymal stem cells in lung. FGF-10 belongs to the heparin binding FGF family, and is also known as Keratinocyte Growth Factor-2 (KGF-2). It shares homology with KGF, and both KGF and FGF-10 activate the receptor FGFR2-IIIb. However, unlike KGF, which induces the proliferation and differentiation of various epithelial cells, FGF-10 is an essential factor for the budding and branching morphogenesis during multi-organ development via mesenchymal-epithelial interactions. FGF-10 is crucial for lung and limb development and is regulated by Shh during early development.

Safety & Handling
This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. For research use only.
This protein was produced in E. coli expression system. Expression system selection determines glycosylation profile, folding, and post-translational modifications. For cell-based stimulation assays, verify the expression system matches the glycosylation requirements of your target receptor or pathway.
Reconstituted in ddH2O at 100 μg/mL. Reconstitute in sterile distilled water or PBS at 100 µg/mL as a standard starting concentration. Allow to dissolve at 4°C for 30 minutes without vortexing. Prepare working aliquots in 0.1% BSA carrier protein and store at −80°C.
This protein has been validated for functional bioactivity: ED50 < 10 ng/mL, measured by a cell proliferation assay using 4MBr-5 cells, corresponding to a specific activity of > 1.0× 10ˆ5 units/mg.. Optimal working concentrations may vary depending on your cell type, assay format, and culture conditions. Titrate the protein in a dose-response experiment to determine the optimal concentration for your system.
Endotoxin level is < 0.2 EU/μg, determined by LAL method. as determined by the LAL method. Low endotoxin is critical for cell-based studies because endotoxin activates NF-κB and TLR4 signalling in immune cells, producing artefactual cytokine induction that can completely mask the true biological activity of the recombinant protein.
Lyophilized recombinant mouse Fibroblast Growth Factor-10 (rmFGF-10) remains stable up to 6 months at -80°C from date of receipt. Upon reconstitution, rmFGF-10 remains stable up to 2 weeks at 4°C or u Upon receipt, immediately store at −80°C. Prepare single-use working aliquots to avoid repeated freeze-thaw cycles. Lyophilized protein is stable for 6–12 months at −80°C from the date of receipt.
