Description
THIS PRODUCT IS STRICTLY FOR RESEARCH AND LABORATORY USE ONLY
IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a synthetic, recombinant analog of human insulin-like growth factor-1 (IGF-1), engineered to have altered binding characteristics and extended activity in experimental systems[1]. It consists of 83 amino acids, compared to the 70 amino acids of mature native IGF-1, and carries two deliberate structural modifications: a glutamic acid-to-arginine substitution at position 3 of the native sequence, and the addition of a 13-amino acid extension peptide (MFPAMPLLSLFVN) at the N-terminus.
