Description
IGF-1 LR3 overview
IGF-1 LR3 (Long R3 IGF-1) is an 83-amino-acid analog of insulin-like growth factor 1 with an arginine at position 3 and a 13-amino-acid N-terminal extension. These changes reduce binding to IGF-binding proteins, which is why it is widely used in cell-culture and growth-factor signalling research.
