FGF1 drives mitogenic signaling through all four FGF receptor subtypes, making it uniquely versatile among FGF family members for receptor-ligand binding studies, including SPR and competition ELISAs. This tag-free recombinant human FGF1, covering the full mature protein (aa 16–155), demonstrates potent bioactivity with an ED50 of 0.2–2 ng/mL in BALB/c 3T3 proliferation assays, confirming its suitability for cell proliferation and survival experiments, neuronal or osteogenic differentiation protocols, and angiogenesis or wound healing models. Because FGF1 is not glycosylated in its native form, E. coli expression yields a protein that is structurally authentic while maintaining cost-effective production at high yield. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for sensitive cell-based assays and supports use as a reliable standard in antibody characterization workflows.
