IGF-1 LR3 (Receptor Grade) 1mg

IGF-1 LR3 (Receptor Grade) 1mg — Ultra-Pure Long R3 Insulin-Like Growth Factor-1 Reference Standard

IGF-1 LR3 (Receptor Grade) is an exceptionally refined structural analogue of endogenous human IGF-1. Specifically engineered with an arginine substitution at position 3 and a 13-amino acid N-terminal extension peptide, this ultra-pure 1mg lyophilized configuration represents the highest standard for definitive receptor binding, affinity profiling, and metabolic signaling assays.

• Receptor-Grade Precision: Synthesized to a premier baseline purity of $\ge 99\%$ verified by rigorous HPLC and Mass Spectrometry testing, keeping your laboratory assays consistent with strict standards on the Peptide Sciences Official platform.

• Minimized Binding Protein Affinity: The specialized structural modifications dramatically lower the peptide’s affinity for IGFBP protein complexes, maximizing receptor bioavailability and significantly extending its biological half-life during in vitro configurations.

• Key Research Fields: Highly utilized in musculoskeletal biology, cellular differentiation, and endocrinology models to evaluate cellular hyperplasia, accelerated protein synthesis signaling, skeletal muscle tissue hypertrophy, and systemic nutrient transport dynamics.

• Optimal Lyophilized Architecture: Supplied in a sterile, freeze-dried powder format to protect the delicate 83-amino acid recombinant structure against environmental degradation, ensuring accurate reconstitution parameters for low-volume testing cohorts.
