Description : Long R3 IGF-1 (LR3 IGF-1) is a synthetic analog of IGF-1 that is generated by modifying the AA sequence for mature human IGF-1. These modifications include the substitution of an Arg for Glu at position three of the mature IGF-1 sequence and the addition of a thirteen aa N-terminal extension, which is derived from methionyl porcine Growth Hormone. These aa changes generate a protein that is still capable of binding to IGF-1 and Insulin receptors, but shows considerably lower affinity binding to IGFBPs compared to wild-type IGF-1. As a result, LR3 IGF-1 has an increased half-life and displays increased biological potency compared to IGF-1.
