🔬 Keratinocyte Growth Factor (KGF | FGF-7 | HBGF-7) plays a central role in epithelial development, tissue repair, and postnatal growth. Known for its potent and selective activity on keratinocytes, KGF remains a key tool in epithelial biology and regenerative research.
🧪 ISOkine® recombinant human KGF is produced under animal-free (AOF/ACF) conditions and validated through functional bioactivity testing, delivering both defined composition and dependable performance.
📊 Bioactivity profile
Assayed via dose-dependent proliferation of 4MBr5 rhesus monkey epithelial cells:
• ED50 typically < 60 ng/mL
• Clear and reproducible dose-response
• Cross reactivity consistent with FGF family members
Each batch is tested for bioactivity and verified to demonstrate comparable activity to a commercial reference standard, supporting confidence and consistency across studies.
⚙️ Formulation details
• PBS, pH 7.2
• Sterile filtered through a 0.2 µm filter
🌎 ISOkine® recombinant human KGF (animal-free) is available in North America through Sapphire North America.
