IGF-1 LR3 Research Peptide — 1mg Lyophilized
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a synthetic, extended analog of human IGF-1 with an additional 13-amino acid extension at the N-terminus and an arginine substitution at position 3. This modification significantly reduces binding to IGF binding proteins (IGFBPs), extending its half-life in research models compared to native IGF-1.
IGF-1 LR3 has been extensively used in cell biology and biotechnology research for the study of IGF-1 receptor signaling pathways, cell proliferation models, and anabolic signaling cascades. Its extended activity makes it particularly valuable for in vitro cell culture research applications.
