Extension of the native insulin-like growth factor-1 sequence by 13 amino acids and substitution of glutamic acid-3 with arginine produced a structurally distinct analogue central to IGF-1 receptor signalling studies. IGF-1 LR3, also known as Long R3 IGF-1 (CAS 946870-92-4), is an 83-amino acid peptide with a molecular weight of 9117.55 g/mol. These modifications reduce affinity for IGF-binding proteins. Produced via solid-phase peptide synthesis.
In vitro studies using cell lines expressing IGF-1R have investigated Akt/PKB and PI3K pathway activation in the relative absence of IGFBP interference. In vivo rodent models have explored tissue-specific IGF-1R engagement by comparing the biodistribution and signalling footprint of IGF-1 LR3 against the native 70-amino acid ligand.
Manufactured in a cGMP compliant laboratory to a guaranteed purity of 98% or above. Every batch undergoes independent testing using HPLC and MS-UPLC analysis before dispatch. Vials are vacuum sealed and stored in a temperature controlled, monitored cold storage system. Certificates of Analysis are available on request.
