IGF-1 LR3 (Long Arginine 3-Insulin-like Growth Factor-I) intended for analytical and laboratory use.

Key Features

• Enhanced Potency: Features a 13-amino acid N-terminal extension and an Arg3 substitution, which significantly reduces its affinity for IGF-binding proteins (IGFBPs).
• Extended Half-Life: The structural modifications allow the peptide to remain biologically active in a research medium for 20–30 hours, compared to the roughly 20-minute half-life of native IGF-1.
• High Purity Standards: Most laboratory-grade preparations maintain a purity level of 99% or higher, verified through HPLC and MS analysis.
• Solubility: Formulated for high solubility in dilute acetic acid or sterile water, facilitating easy reconstitution for in-vitro assays.

Technical Specifications

• Molecular Formula: C₄₀₀H₆₂₅N₁₁₁O₁₁₅S₉.
• Molecular Weight: Approximately 9,111 Da to 9,200 Da.
• Sequence: 83 amino acids in a single polypeptide chain.
• CAS Number: 946870-92-4.
• Appearance: Supplied as a lyophilized white powder.
• Storage Requirements: Stable at room temperature for up to 3 weeks; long-term storage is recommended at -20°C.

Available Configurations

• IGF-1 LR3 0.1mg Vial: A small-scale configuration suitable for initial testing or single-use analytical applications.
• IGF-1 LR3 1mg Vial: The most common standard research configuration, typically used for cell culture studies.
• Recombinant Human IGF-1 LR3 (Bulk): Available in 5mg (5000 µg) increments for large-scale laboratory operations or animal-free recombinant protein needs.
