This is a specialized research product of IGF-1 LR3, a synthetic analog of human Insulin-like Growth Factor-1, strictly intended For In Vitro Research Use Only — Not for Human or Veterinary Use.


Description & Application

  • Description: IGF-1 LR3 is a synthetic, 83-amino acid analog of human IGF-1. It has been modified by the substitution of an Arginine for Glutamic Acid at position 3 and the addition of a 13-amino acid extension peptide at the N-terminus.

  • Mechanism: These modifications significantly decrease the peptide's affinity for IGF-binding proteins (IGFBPs). In research settings, this results in a much higher concentration of "free" IGF-1 and a significantly extended half-life (approximately 20–30 hours) compared to standard IGF-1.

  • Research Focus: It is a primary tool for studying:

    • Muscle hyperplasia and the proliferation of satellite cells.

    • Protein synthesis and cellular growth signaling pathways (PI3K/Akt/mTOR).

    • Glucose and amino acid transport into cells.

    • Tissue repair and systemic anabolic modeling in in vitro environments.


Specifications & Storage

  • Unit Size: 1mg (lyophilized powder, single vial).

  • Form: Lyophilized powder.

  • Solubility: Soluble in sterile water or research-compatible buffers (e.g., 10mM HCl or acetic acid for initial dissolution).

  • Storage (Dry): Store in a cool, dry environment (preferably $-20^{\circ}\text{C}$ for long-term stability).

  • Storage (Reconstituted): Once reconstituted, the solution must be refrigerated at $2^{\circ}\text{C}–8^{\circ}\text{C}$ and used within a short research window to prevent degradation.


⚠️ Legal & Intended Use
