What Is IGF-1 LR3?

IGF-1 LR3 is a modified form of insulin-like growth factor-1 containing an arginine substitution at position 3 and a 13-amino-acid extension at the N-terminus. These structural modifications provide greater stability and reduced binding to IGF-binding proteins compared with native IGF-1.

Because of these characteristics, IGF-1 LR3 has become one of the most widely studied growth factor analogs in biomedical research.

Key Facts

• Synthetic analog of IGF-1
• Contains 83 amino acids
• Extended biological activity compared with native IGF-1
• Reduced affinity for IGF-binding proteins
• Supplied as a 1 mg lyophilized vial
• High-purity analytical testing
