IGF-1LR3 1mg

IGF-1 LR3 is engineered as an extended-activity analog of human Insulin-like Growth Factor-1, incorporating an N-terminal 13-amino-acid extension and an Arg3 substitution to bypass binding protein inactivation and facilitate specialized cellular growth studies.

• IGFBP Resistance & Extended Bioavailability: Dramatically reduces binding affinity for IGF-binding proteins (IGFBPs), extending the active biological window from 20 minutes to 20–30 hours for sustained receptor engagement.

• Satellite Cell Proliferation & Hyperplasia: Drives potent satellite cell activation and local protein synthesis, optimizing research into myogenesis, tissue repair pathways, and skeletal muscle fiber creation.

While endogenous IGF-1 is rapidly neutralized by circulating binding proteins, IGF-1 LR3’s structural modifications prevent IGFBP sequestration without compromising receptor affinity—allowing researchers to investigate sustained anabolic signaling, enhanced nutrient partitioning, and tissue regeneration without rapid clearance limitations.
