Medchemexpress LLC FGF-12 Human 181a. 50ug
Recombinant human FGF-12 (181 amino acids) is a His-tagged protein expressed in E. coli, supplied lyophilized and characterized for high purity, low endotoxin, and verified biological activity. It is intended for in vitro signaling and functional studies involving neuronal excitability and regulation of voltage-gated sodium channels.
- Highly pure protein (>95% by reducing SDS-PAGE).
- Low endotoxin level (<1 EU/μg) suitable for cell-based assays.
- Biologically active with ED50 ≈1.7 ng/mL in a standard proliferation assay.
- Lyophilized from a buffered formulation to enhance stability.
- N-terminal 6xHis tag enables straightforward purification and detection.
- Stable when stored lyophilized at -20°C; aliquot and freeze after reconstitution for long-term storage.
