About IGF-1 LR3

IGF-1 LR3 (Long R3 IGF-1) is an 83-amino-acid analog of insulin-like growth factor-1, modified with an arginine substitution and an N-terminal extension that reduce binding to IGF-binding proteins and extend its activity. This design makes it a prolonged-action tool for studying IGF-1 receptor signaling in cell and tissue models.

Researchers investigate IGF-1 LR3 in models of cellular proliferation, protein synthesis, growth signaling, and metabolic regulation. It is supplied as a lyophilized powder intended for reconstitution under controlled laboratory conditions, tested to ≥98% purity with a certificate of analysis available on request. This product is sold strictly for research use only and not for human consumption.
