What is IGF-1 LR3?

IGF-1 LR3 (Insulin-like Growth Factor-1 Long Arg3) is a synthetically modified variant of the naturally occurring IGF-1 peptide. This recombinant peptide belongs to the family of insulin-like growth factors and consists of 83 amino acids, in contrast to native IGF-1 which contains 70 amino acids. The LR3 variant was developed by the substitution of glutamic acid with arginine at position 3, combined with a 13-amino acid N-terminal extension.

Storage and Handling

Lyophilized IGF-1 LR3 should be stored at -20°C in a dry environment, protected from light. Under these conditions, the peptide remains stable for at least 24 months. For reconstitution, sterile water or saline solution is recommended. After reconstitution, the solution is stable for 7 days at 4°C or up to 30 days at -20°C. Avoid repeated freeze-thaw cycles to minimize peptide degradation. Always use sterile techniques during handling and preparation of solutions.
