IGF-1 LR3 — a long-acting recombinant IGF-1 analog — laboratory research reference and documentation overview.
IGF-1 LR3 (Long R3 IGF-1) is an 83-amino-acid recombinant analog of insulin-like growth factor 1 with an arginine substitution at position 3 and a 13-amino-acid N-terminal extension. The modifications dramatically reduce IGFBP affinity, extending the bioactive half-life relative to native IGF-1.
