IGF-1LR3

IGF-1 LR3 is an 83-amino acid engineered analogue of human IGF-1 with an Arg3 substitution and a 13-amino acid N-terminal extension. It has been widely referenced in published preclinical literature and is manufactured to ≥99% purity with third-party verification.

IGF-1 LR3 is an 83-amino acid engineered analogue of human IGF-1 with structural modifications. It has been widely referenced in published preclinical literature. Supplied as a high-purity lyophilized research protein.

IGF-1 LR3 was engineered as a research tool with structural modifications to the native IGF-1 backbone. The Arg3 substitution and N-terminal extension were designed to create a distinct structural profile. It has become a standard reference compound in published preclinical literature.

This research protein carries the True Research Certified designation, awarded exclusively to compounds that achieve verified ≥99% purity through independent third-party HPLC and mass spectrometry analysis. True Research Certified products undergo batch-level endotoxin screening via the LAL (Limulus Amebocyte Lysate) method and are accompanied by a comprehensive Certificate of Analysis (COA) documenting purity, identity, and endotoxin results. This certification reflects our commitment to supplying only the highest-grade research materials to the scientific community.
