Compound Overview
IGF-1 LR3 is a synthetic 83-amino acid analog of insulin-like growth factor-1 that incorporates an N-terminal extension and a residue substitution within the native IGF-1 sequence framework. It is structurally categorized as a modified IGF-1 class peptide used in experimental systems for receptor-binding characterization and comparative structure–activity relationship evaluation.
In laboratory research contexts, IGF-1 LR3 is utilized in controlled in vitro and animal model workflows to support analytical verification, receptor interaction mapping, and pathway-relevant assay development where IGF-axis peptides are evaluated under standardized conditions. All data referenced on this page is derived from published preclinical animal and in vitro studies. No human clinical trials have established approved uses for IGF-1 LR3 as a research compound.

Handling & Storage
Lyophilized Stability:
When stored sealed in a dry environment protected from light, lyophilized peptide material may maintain chemical stability for up to 12 months at controlled room temperature. For maximum long-term preservation, storage at -20°C is recommended.
Post-Reconstitution Stability:
Following reconstitution under sterile laboratory conditions, the solution may maintain stability for up to 30 days when stored at 2–8°C. Minimize repeated freeze–thaw cycles and protect from light to preserve peptide integrity.
Handling:
Allow vial to equilibrate to room temperature before opening to prevent moisture condensation. Use sterile technique throughout preparation.
