IGF-1 LR3 (Long Arginine 3-IGF-1) – Advanced Recombinant Peptide for Molecular Research
Our IGF-1 LR3 is a highly potent, synthetic analog of the naturally occurring Insulin-like Growth Factor-1 (IGF-1). This specific “Long R3” version is characterized by the substitution of Glutamic acid with Arginine at position 3, along with an additional 13-amino acid extension at the N-terminus. These structural modifications are engineered to prevent the peptide from binding to IGF-binding proteins (IGFBPs), significantly increasing its bioavailability and stability in laboratory research environments.
Technical Superiority and Analytical Purity In the field of molecular biology, precision is everything. Our IGF-1 LR3 100mcg is produced using recombinant DNA technology and purified to a certified standard of 99% or higher. Each vial contains a lyophilized, white powder that has undergone rigorous HPLC and Mass Spectrometry testing to ensure the absence of truncated sequences or contaminants. This ensures that researchers can achieve highly reproducible results in sensitive biochemical assays.
Key Areas of Scientific Investigation Due to its unique pharmacokinetic profile, IGF-1 LR3 is a primary tool for studying:
Cellular Proliferation & Differentiation: Investigating the signaling pathways that regulate cell growth and specialized cell development in-vitro.
Protein Synthesis Pathways: Analyzing the influence of IGF-1 analogs on the mTOR pathway and nitrogen retention in laboratory models.
Receptor Affinity Studies: Exploring the interaction between modified ligands and the Type 1 IGF receptor (IGF-1R) without interference from binding proteins.
Handling and Laboratory Storage The IGF-1 LR3 peptide is highly sensitive to temperature. For long-term integrity, unopened vials must be stored at -20°C. Once reconstituted for research use, the solution should be kept at 2°C to 8°C and handled with extreme care to avoid mechanical agitation, which can denature the complex 83-amino acid structure.
