About This Compound

IGF-1 LR3 is a modified insulin-like growth factor 1 analog carrying a 13-amino-acid N-terminal extension and an Arg substitution at position 3. Both modifications sharply reduce binding to IGF-binding proteins, which is why research uses it to study extended IGF-1 receptor signaling.
