IGF-1 LR3

IGF-1 LR3 (Long R3 IGF-1): The Engineered Super-Agonist for Anabolic & Metabolic Research ⚙️🔥

Amplify the Signal of Growth & Regeneration. IGF-1 LR3 is not the native hormone; it is a synthetically engineered, 83-amino acid analog of Insulin-like Growth Factor-1 (IGF-1) with two critical modifications: an N-terminal 13-amino acid extension and an Arg³→Leu substitution. This design dramatically reduces its binding to inhibitory IGF Binding Proteins (IGFBPs), resulting in a molecule with significantly prolonged half-life and vastly enhanced in-vitro and in-vivo bioactivity. For researchers in muscle physiology, metabolism, and tissue engineering, it represents the definitive tool to study potent, sustained anabolic signaling. 🧬

Imagine Unleashing Uninhibited Growth Factor Action. Native IGF-1's activity is tightly controlled by binding proteins. IGF-1 LR3's "engineered escape" from this regulation allows you to investigate the full, unattenuated potential of the IGF-1 receptor pathway. This makes it indispensable for research in:

• Muscle Hypertrophy & Regeneration: Driving potent myoblast proliferation and differentiation in models of muscle wasting, injury, or athletic performance.

• Metabolism & Nutrient Partitioning: Studying enhanced glucose uptake, protein synthesis, and the interplay between IGF-1 and insulin signaling.

• Cell Culture & Tissue Engineering: Providing a superior, stable growth stimulus for demanding cell proliferation assays and stem cell differentiation protocols.

Maximized Bioactivity Demands Maximum Purity. Research with a super-agonist requires material that guarantees its engineered properties.

• Verified Potency & Structure: ≥97% purity, with the full modified sequence confirmed by HPLC and Mass Spectrometry, ensuring the integrity of its critical extensions. ✅
