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
