IGF-1 LR3 1MG

What is IGF-1 LR3? IGF-1 LR3 (Long R3 Insulin-like Growth Factor 1) is a recombinant 83 amino acid analog of human IGF-1 with an N-terminal extension and Arg substitution at position 3. These modifications dramatically reduce affinity for IGF binding proteins (IGFBPs), extending free serum half-life...
