IGF-1 LR3, also known as Long Arg3 IGF-1, is a recombinant protein analogue of human Insulin-Like Growth Factor-1 that has a molar mass of 9,200 Daltons and is comprised of 83 amino acids. IGF-1 LR3 comprises the complete IGF-1 sequence, but with a 13 amino acid extension on the B-Terminus domain and the substitution of an Arginine for the Glutamic Acid at position 3. The LR3 analogue of IGF-1 was created with the intent to drastically increase the biological activity of the protein and IGF-LR3 is several times more potent than rhIGF-1. This specific sequence alteration has decreased the affinity of binding to the IGFBPs, which control the biological actions of IGF-1 and prevent the protein from reaching the IGF-1 receptors.
