FGF9 plays a critical role in neuronal survival, lung development, and mesenchymal cell proliferation, making it a key tool for dissecting FGF receptor signaling pathways. This tag-free, full-length recombinant human FGF9 (aa 1–208) demonstrates strong mitogenic potency, with an ED50 of 1–5 ng/mL in a Balb/3T3 fibroblast proliferation assay, supporting use in cell proliferation and survival assays, neuronal or osteogenic differentiation studies, and angiogenesis or wound healing models. Produced in *E. coli*, the protein lacks eukaryotic glycosylation—an advantage when researchers need to isolate FGF9–FGFR binding kinetics from glycan-mediated effects in SPR or ELISA-based receptor-ligand competition assays. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for sensitive cell-based experiments and provides a suitable basis for use as an ELISA standard or in *in vivo* tumor biology models.
