IGF-1 LR3 (1mg)

IGF-1 LR3 (1mg): Product Description

IGF-1 LR3, or Long R3 Insulin-Like Growth Factor 1, is a synthetic 83-amino-acid analog of human IGF-1. It contains an arginine substitution at the third position and an additional 13-amino-acid extension at the N-terminus. These structural modifications distinguish it from native IGF-1 and influence its interaction with IGF-binding proteins in experimental systems.

Laboratory research involving IGF-1 LR3 may examine IGF-1 receptor activation, intracellular signaling through PI3K/AKT and MAPK-related pathways, cellular proliferation, differentiation, protein-synthesis signaling and glucose-associated cellular processes. Researchers may also compare its binding and stability characteristics with native IGF-1 under controlled assay conditions.

Because IGF-1 LR3 is a comparatively large peptide, reported molecular formulas can vary depending on sequence conventions, disulfide-bond representation and chemical form. The precise amino-acid sequence and measured molecular mass listed on the product’s Certificate of Analysis should therefore take priority over generalized database values.
