IGF-1 LR3 1mg


IGF-1 LR3 is an insulin growth factor and is a human recombinant. It is an analog of 83 amino acids of human IGF-I that really completes the sequence of human IGF-1 but with the substitution of an Arg for Glu in position 3. As well, as a 13 amino acid extension peptide at the N-terminus. This makes Long R3 IGF-I significantly more potent -B about 2 times than IGF-I. In studies, so far it has shown a lower affinity for being inactivated by IGF-binding proteins and, greater activity in the body.
