IGF-1-LR3 1 mg

Research Profile

Engineered with an arginine substitution at position 3 and a 13-amino acid N-terminal extension, this analog exhibits dramatically reduced binding to IGF-binding proteins (IGFBPs), resulting in substantially increased bioavailability and receptor engagement in research models. It is widely used as a potent reference standard in cell proliferation, metabolic signaling, and growth factor research.
