IGF-1 LR3 1mg

IGF1-LR3 (insulin-like growth factor-1 long arginine-3) is a synthetic analog of insulin-like growth factor-1 engineered for use in laboratory research. Structural modifications include N-terminal amino acid extension and substitution of glutamic acid with arginine at position three, resulting in reduced affinity for IGF-binding proteins. These modifications extend molecular persistence in experimental systems, enabling prolonged interaction with IGF-associated receptors in controlled in-vitro and in-vivo animal models.

Preclinical research utilizes IGF1-LR3 as a tool compound to investigate growth factor–mediated signaling, cellular proliferation pathways, differentiation programs, and metabolic signaling cascades. All discussion herein is limited to experimental research contexts and does not imply applied, therapeutic, or physiological use.
