Research Overview
IGF-1 LR3 (Long Arginine 3 IGF-1) is a recombinant 83-amino-acid analog of human insulin-like growth factor 1. An N-terminal extension and an arginine substitution at position 3 reduce binding to IGF-binding proteins, extending the molecule's research half-life relative to native IGF-1.
Mechanism of Action
Binds the IGF-1 receptor (IGF-1R) and activates PI3K/Akt and MAPK signaling cascades in research models, supporting studies of cellular proliferation and protein synthesis.
Research Applications
- IGF-1 receptor signaling research
- PI3K/Akt cascade studies
- Cellular proliferation models
