IGF1-LR3 1mg

IGF-1 LR3, or Long R3 IGF-1, is a synthetic analogue of insulin-like growth factor 1. It is a single-chain polypeptide of 83 amino acids with the molecular formula C400H625N111O115S9 and a molecular weight of approximately 9117.5 g/mol. It differs from native IGF-1 by an arginine substitution at position 3 and a 13-residue N-terminal extension. Oasis Labs supplies it as a lyophilized powder at 99%+ documented purity for laboratory research use only, with lot-specific identity confirmed on the Certificate of Analysis.

Published preclinical literature has examined IGF-1 LR3 as a ligand at the IGF-1 receptor, with reported work in in vitro and animal models concerning receptor binding and downstream signalling in those experimental systems. The structural modifications are reported in that literature to reduce its binding to IGF binding proteins relative to native IGF-1. Oasis Labs supplies this material strictly as a research reagent. No human or veterinary use is described, supported or intended.

IGF-1 LR3 is a polypeptide, a chain of 83 amino acids with a molecular weight of approximately 9117.5 g/mol. That places it in the polypeptide class, which is structurally unrelated to small molecule classes such as the steroids, built on a four-ring carbon structure and typically under 500 g/mol. Oasis Labs supplies IGF-1 LR3 as a research reagent only.
