Key Features & Benefits

• Ultra-High Purity: ≥99% purity verified by SDS-PAGE, ensuring minimal contaminants and consistent experimental results
• Completely Animal-Origin-Free: Recombinant expression system eliminates risks of BSE, viral contamination, and immunogenic impurities associated with plasma-derived transferrin
• Iron-Free (Apo) Form: Ideal for use in iron-supplemented basal media; binds free iron to prevent oxidative damage and ROS formation
• High Batch Consistency: Strict quality control across production ensures reproducible performance lot after lot
• Low Endotoxin: Manufactured under controlled conditions to meet stringent cell culture and bioprocessing requirements
• Wide Solubility Range: Readily soluble in aqueous solutions, clear and colorless after reconstitution
• Verified Identity: Confirmed positive by Western blotting, authentic human transferrin structure and bioactivity

Applications
