IGF LR3 Research Material
IGF LR3, also written Long R3 IGF-I in scientific literature, denotes an engineered analogue of human insulin-like growth factor I. Literature descriptions identify an 83-amino-acid protein-form material comprising an IGF-I sequence with an Arg substitution at position 3 and a 13-residue N-terminal extension. It should not be characterized as a conventional short synthetic peptide.
Published studies describe Long R3 IGF-I as having reduced affinity for several IGF-binding proteins relative to native IGF-I in experimental systems. That background does not establish the identity, activity, clinical safety or suitability of an individual catalogue lot.

Identity and Documentation
“IGF LR3” alone is not a complete material specification. Before use, laboratories should confirm the stated sequence or construct, molecular form, expected molecular mass, lot identifier and accompanying analytical documentation. Identity, content, purity and activity are separate attributes and should not be inferred from one another.
Handling
Follow the storage condition stated for the specific product and lot. Do not infer reconstituted-solution stability from conditions stated for dry material. Review our laboratory storage and handling guide and browse GH Research Peptides.
