IGF-1 Lr3

IGF-1 LR3 (Insulin-Like Growth Factor-1 Long Arg³) is a synthetic analog of human IGF-1, structurally modified to enhance stability and extend biological activity compared to native IGF-1. These modifications reduce binding to IGF-binding proteins, allowing prolonged interaction with target receptors in experimental settings.

IGF-1 LR3 is widely referenced in cellular, metabolic, and growth-factor research, particularly in studies examining cell signaling, proliferation pathways, and anabolic mechanisms. Its extended activity profile makes it a common subject of investigation in laboratory models requiring sustained receptor engagement.
