Scientific Background
Fibroblast Growth Factor-16 (FGF-16) is a heparin binding growth factor, a member of the FGF family. All FGF family members are heparinbinding growth factors with a core 120 amino acid (aa) FGF domain that allows for a common tertiary structure. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. The rat homolog is predominantly expressed in embryonic brown adipose tissue and has significant mitogenic activity, which suggests a role in proliferation of embryonic brown adipose tissue.

Functional Activity
Measured in a cell proliferation assay using 3T3 mouse fibroblast cell, The ED50 for this effect is < 20 ng/mL.
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 Mammalian (CHO Cells) 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 or PBS 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: Measured in a cell proliferation assay using 3T3 mouse fibroblast cell, The ED50 for this effect is < 20 ng/mL.. 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 Human Fibroblast Growth Factor-16 remains stable up to 6 months at -80°C from date of receipt. Upon reconstitution, Human Fibroblast Growth Factor-16 should be stable up to 1 w 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.
