IGF-1 LR3 0.1mg

Description

IGF-1 LR3 (Long R3 IGF-1) is an 83-amino-acid analog of human insulin-like growth factor-1 with an arginine substitution at position 3 and a 13-amino-acid N-terminal extension, which reduces binding to IGF-binding proteins and extends its activity in research systems. It is studied in cell-growth, muscle, and tissue-repair models and is widely used as a defined cell-culture supplement.

Areas of Research

• Growth-Factor Signaling — studied for IGF-1 receptor activation and downstream PI3K/Akt and MAPK pathways.
• Cell Proliferation — investigated for effects on cell growth, survival, and differentiation in vitro.
• Muscle & Tissue Research — examined in skeletal-muscle, satellite-cell, and tissue-repair models.
• Cell-Culture Applications — used as a serum-free media supplement in recombinant protein and cell-line work.
• IGFBP Interaction — studied for its reduced affinity for IGF-binding proteins versus native IGF-1.

Product Care & Storage

• All products are shipped lyophilized, which keeps them stable for shipping for up to 3–4 months. Products must be reconstituted to a liquid by mixing with bacteriostatic water for research and testing.
• Lyophilized / powder form — Store in a cool, dry place away from light; stable at room temperature for several weeks. For long-term storage (months to years), freezing is optimal.
• Reconstituted form — Refrigerate under 39°F; remains stable for up to 30 days.
• Usage — We are unable to provide any dosing instructions; however, all products should be considered pharmaceutical grade.
