Research Overview

IGF-1 LR3, also known as Long R3 IGF-1, is an engineered analogue of human insulin-like growth factor 1. It contains an arginine substitution at position 3 and an additional 13-amino-acid N-terminal extension, giving the molecule a total length of 83 amino acids. It is frequently studied in laboratory models examining IGF-1 receptor signalling, reduced binding affinity to insulin-like growth factor binding proteins, cellular growth pathways, differentiation processes, and growth factor-mediated biological responses.

• Studied in experimental models involving IGF-1 receptor signalling and growth factor pathway activity.
• Investigated in cell proliferation, differentiation, and survival pathway research.
• Used in laboratory studies examining insulin-like growth factor binding protein interactions.
• Included in research involving tissue, muscle, bone, connective tissue, and cellular growth models.
• Explored in controlled studies involving peptide stability, receptor response, and pathway-specific biological signalling.

Researchers frequently select IGF-1 LR3 for controlled experimental models requiring a professionally handled, independently verified research product with transparent quality documentation.
