IGF-1 LR3 99%+ High Purity Cosmetic Raw Material Multiple Sizes: 0.1 mg / 1 mg per Vial

Product Description

IGF‑1 LR3 (Long Arginine 3‑Insulin‑like Growth Factor‑1, also known as Long‑R³‑IGF‑I) is a recombinant synthetic analogue of human IGF‑1, engineered for enhanced stability and bioavailability. The molecule is an 83‑amino‑acid single‑chain polypeptide with a molecular weight of approximately 9,117.5 g/mol. The engineering comprises two key modifications: (1) an N‑terminal 13‑amino‑acid extension (MFPAMPLLSLFVN), and (2) a substitution of glutamic acid with arginine at position 3 (the “R3” mutation). Together, these modifications reduce binding affinity to IGF‑binding proteins (IGFBPs) by approximately 1000‑fold, resulting in a dramatically increased free‑peptide concentration in the cellular environment and an extended half‑life (20‑30 hours compared to 12‑15 hours for native IGF‑1), while preserving full agonist activity at the IGF‑1 receptor.
