Product Overview

IGF-1 LR3 (CAS 946870-92-4), also known as Long Arg3 Insulin-like Growth Factor-1, is a synthetic, recombinant analogue of endogenous human IGF-1 that has been structurally modified to include an 83 amino acid sequence. By replacing the glutamic acid at position 3 with an arginine and adding a 13 amino acid extension at the N-terminus, this peptide exhibits a significantly decreased affinity for insulin-like growth factor-binding proteins. Within the Peptides and advanced biochemical research sectors, it is highly valued for its enhanced metabolic stability, extended biological half-life, and potent technical role in activating the IGF-1 receptor pathway to study cellular proliferation and differentiation in laboratory models. As a leading manufacturer of IGF-1 LR3 CAS 946870-92-4 based in China, Conscientia Industrial utilizes precision recombinant technology, solid-phase peptide synthesis (SPPS) optimization, and multi-stage high-performance liquid chromatography purification to ensure the highest structural integrity and exact amino acid alignment. Our product maintains a exceptionally strict purity profile to meet demanding global technical requirements for peptide-based assay development, laboratory evaluation, and advanced chemical research.
