Description

IGF-1 LR3 1mg – Long-Acting Growth Factor Research Peptide

IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a modified analog of human IGF-1 developed for laboratory investigations involving cellular proliferation, differentiation, protein synthesis, and tissue regeneration. Compared with native IGF-1, IGF-1 LR3 contains an arginine substitution at position 3 and a 13-amino-acid N-terminal extension, modifications that substantially reduce its affinity for IGF-binding proteins and prolong its biological activity in research models.

Researchers utilize IGF-1 LR3 to study activation of the IGF-1 receptor (IGF-1R) and downstream signaling pathways including PI3K/Akt/mTOR and MAPK/ERK. These pathways regulate numerous cellular processes involved in growth, survival, metabolism, and protein synthesis. Ongoing investigations continue to explore its role in skeletal muscle biology, connective tissue research, stem cell function, glucose metabolism, and cellular regeneration.

Cellular Genix Labs manufactures IGF-1 LR3 1mg using advanced peptide synthesis techniques and stringent quality-control standards to ensure consistent purity and reproducibility for laboratory research.
