IGF-1 LR3: Long-Acting Insulin-Like Growth Factor Analogue

Global Peptides supplies research grade IGF-1 LR3 to laboratories across Australia, supporting studies into IGF-1 receptor signalling, cellular growth pathways and cell culture research.

IGF-1 LR3 is a recombinant analogue of insulin-like growth factor 1, engineered for greater stability and potency in laboratory systems. Two modifications drive this: an arginine substitution at position 3 and a 13 amino acid extension at the N-terminus, which together produce an 83 amino acid molecule.

Each batch is produced under controlled manufacturing conditions and undergoes independent laboratory verification, supporting consistent, repeatable results across analytical testing. A Certificate of Analysis is available on request for every order.

What is IGF 1 LR3 Peptide?

Researchers often ask how this analogue differs from native insulin-like growth factor 1 and why it is preferred in many experimental systems.

The structural changes sharply reduce the molecule's affinity for IGF binding proteins, which normally bind and neutralise free growth factor. With less binding, the analogue stays active for hours rather than minutes in experimental models and shows greater potency than the native form.

This extended activity is why it is widely used as a supplement in cell culture media and as a reference compound in IGF-1 receptor signalling studies.
