Product Information
IGF-1 LR3 – Research Grade Peptide
Lyophilised Powder | ≥99% Purity
IGF-1 LR3 (Long Arg3 IGF-1) is a synthetically manufactured research peptide supplied as a high-purity lyophilised powder. It is characterised as a modified insulin-like growth factor-1 (IGF-1) analogue and is supplied strictly for laboratory and analytical research applications.
Research Context
IGF-1 LR3 is studied in laboratory environments for its interaction with the insulin-like growth factor signalling axis. It is characterised as a long-acting IGF-1 receptor agonist analogue, engineered via:
• An arginine substitution at position 3 (Arg3)
• An additional 13–amino acid N-terminal extension (“Long”)
In experimental models, these modifications are investigated for their potential to reduce affinity for IGF-binding proteins (IGFBPs) and improve peptide stability, supporting sustained interaction with the IGF-1 receptor (IGF-1R) under controlled research conditions.
Research interest in this class of peptides primarily focuses on understanding:
• IGF-1 receptor (IGF-1R) activation and downstream signalling
• PI3K/AKT and MAPK pathway involvement in cell growth models
• Cellular proliferation, differentiation, and survival signalling in vitro
• Ligand stability and binding dynamics relative to native IGF-1
Any reference to receptor activity or biological mechanisms is provided strictly for scientific context within research settings.
