Description
IGF-1 LR3
For Research Use Only | Not for Human or Veterinary Use
Description:
IGF-1 LR3 is a synthetic 83-amino-acid analogue of human insulin-like growth factor 1, featuring enhanced potency and metabolic stability compared to native IGF-1. This compound contains an arginine substitution at position 3 (Arg³) and a 13-amino-acid N-terminal extension, resulting in reduced IGFBP (insulin-like growth factor binding protein) affinity and approximately 3-fold enhanced potency. The extended half-life of 20-30 hours enables sustained IGF-1 receptor signaling in experimental models, making it suitable for research into cell proliferation, anabolic signaling, body composition, and metabolic regulation.
