About the compound

IGF-1 LR3

IGF-1 LR3 is a synthetic 83-residue analog of insulin-like growth factor-1 with an N-terminal extension and arginine substitution at position 3. The modifications reduce binding to IGF-binding proteins, extending in-vitro receptor availability.

Auralen does not publish protocols, dosing, or human-use instructions. This material is supplied as a reference standard for in-vitro biochemical research only.
