IGF-1 LR3

Meaning

IGF-1 LR3, or Long R3 Insulin-like Growth Factor-1, is a synthetic analog of human Insulin-like Growth Factor-1. This modified peptide features an arginine substitution at position three and an N-terminal thirteen-amino acid extension. These alterations extend its half-life and reduce IGFBP binding, increasing bioavailability and IGF-1 receptor interaction.
