Long R3 IGF-1
IGF-1 LR3
IGF-1 LR3 is a synthetic long-chain analog of human IGF-1 in which the glutamic acid at position 3 is replaced by arginine and a 13-amino-acid N-terminal peptide is added, lowering binding-protein affinity. It is studied in vitro in growth-signalling pathways (PI3K/Akt/mTOR) and cellular proliferation. Supplied as a lyophilized reference standard for laboratory research.
