Real Peptides IGF-1 LR3

$89.99

IGF-1 LR3 (Long R3 insulin-like growth factor 1) is a recombinant analog of insulin-like growth factor 1 modified for reduced binding-protein affinity. It has been characterized in preclinical research as an IGF-1 receptor agonist, making it a useful tool compound for isolating growth-factor signaling endpoints in experimental designs.

IGF-1 LR3 has been used in preclinical in vitro and rodent model studies to investigate IGF-1 receptor signaling, cellular proliferation and differentiation, protein synthesis pathways, and metabolic endpoints. Its extended activity profile supports mechanistic characterization of growth-factor biology in cell-based and rodent research.

Intended use: In vitro and preclinical in vivo laboratory research only. Not approved for human or veterinary use.
