IGF-1LR3
Research use only.
IGF-1 LR3 is a longer-lasting, lab-made version of Insulin-like Growth Factor 1, a hormone the body uses for growth and repair. The LR3 change helps it stay active longer, which makes it useful in research.
What it is studied for
- Muscle growth: how it signals cells to grow and repair.
- Recovery: tissue repair in research models.
- Cell studies: a common tool in laboratory growth research.
About IGF-1LR3
IGF-1 LR3 (Long R3 IGF-1) is an 83-amino-acid analog of insulin-like growth factor 1. An arginine substitution at position 3 plus a 13-amino-acid N-terminal extension sharply reduce binding to IGF-binding proteins, so far more of the peptide stays free and active — which is why it is a standard reagent in cell-culture and IGF-1 receptor research.
Key research areas
- IGF-1R signalling — PI3K/Akt and MAPK pathway activation downstream of the IGF-1 receptor.
- Cell culture & bioprocessing — A long-acting growth supplement for cultured cell lines.
- Cellular growth research — Proliferation and differentiation models.
- Binding-protein studies — How reduced IGFBP binding changes bioavailability.

Frequently asked questions
What does "LR3" mean?
"Long R3": an arginine (R) at position 3 plus a 13-amino-acid extension. Together they reduce IGF-binding-protein binding and extend the peptide’s activity.
What is IGF-1 LR3 studied for?
IGF-1 receptor signalling, cell-culture growth support and cellular proliferation research.
How is it supplied?
As a 1mg lyophilized vial, HPLC-tested with a per-batch certificate of analysis.
Is IGF-1 LR3 for human use?
No. It is sold strictly for laboratory research use only.
Related research compounds
