IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is an 83-amino-acid analog of human IGF-1. It carries an arginine substitution for glutamate at position 3 together with a 13-residue N-terminal extension - modifications that reduce binding to IGF-binding proteins and extend the analog's in-vitro stability relative to native IGF-1. It is supplied as a lyophilized powder for laboratory research use only.
In the research literature, IGF-1 LR3 is used as a reference ligand for studying IGF-1 receptor signaling, the PI3K/Akt and MAPK cascades, and cellular proliferation and differentiation in cultured-cell systems. It is a common tool compound in growth-factor pharmacology, receptor-binding assays, and structure-activity studies. Not for human or veterinary use.
Store lyophilized powder at -20C protected from light and moisture; for extended storage -80C is recommended. Aliquot reconstituted solutions and keep frozen to minimize freeze-thaw cycles.
For laboratory research use only. Reconstitute in dilute acetic acid or sterile water per assay requirements; avoid repeated freeze-thaw cycles.
