About this compound
IGF-1 LR3 is a synthetic 83-amino-acid analogue of insulin-like growth factor-1 with an arginine substitution at position 3 and a 13-residue N-terminal extension. These changes reduce binding to IGF-binding proteins, which is why it is widely used in cell culture to study IGF-1 receptor signalling. It is a standard tool compound in in vitro growth and proliferation assays.

Preclinical research references
Provided for informational context only. All cited studies involve preclinical or in vitro models. Results do not predict human safety or efficacy. These references do not constitute medical claims.
- Cell culture work uses IGF-1 LR3 as a long-acting IGF-1 receptor agonist in serum-free media for proliferation and survival assays
- Binding studies show reduced affinity for IGF-binding proteins compared with native IGF-1, giving a higher effective potency in vitro
- Preclinical work has examined IGF-1 receptor signalling through the PI3K/Akt and MAPK pathways in muscle and other cell models
