Product Description
IGF-1 LR3 is a synthetic recombinant protein analog, not a simple short peptide. It is an 83-amino-acid analog of human IGF-1 that includes an arginine substitution at position 3 and a 13-amino-acid N-terminal extension, and it is commonly supplied as a non-glycosylated lyophilized protein for laboratory use. Supplier references describe it as a defined research material used in cell signaling, receptor-pathway studies, and controlled formulation workflows.
Research interest in IGF-1 LR3 centers on its interaction with the IGF-1 receptor, its reduced affinity for insulin-like growth factor binding proteins (IGFBPs) relative to native IGF-1, and its use in cell-culture and growth-factor signaling models. Supplier and technical references position it in workflows involving cell proliferation assays, media supplementation, and recombinant protein evaluation, with one R&D Systems datasheet specifically reporting activity in an MCF-7 human breast cancer cell proliferation assay and noting that IGFBP-3 does not inhibit its activity under that test system.
