IGF-1 LR3, also known as Long-Arginine-3-IGF-1, is an analogue of human IGF-1 that has been modified to include a 13 amino acid N-terminus extension and the substitution of Arginine for Glutamic Acid at position 3. As a result of these modifications, IGF-1 LR3 is approximately three times more potent than IGF-1 and possesses an increased half-life due to lowered affinity for binding to the Insulin-Like Growth Factor-Binding Proteins (IGFBPs). IGF-1 LR3 retains the ability to bind agonistically to the IGF-1 receptor with improved metabolic stability, relative to IGF-1.

The supplementation of mammalian cell cultures with Long R3 IGF-1 at a much lower concentration results in more highly elevated productivity than with standard concentrations of insulin and/or standard IGF-1. IGF-1 LR3 is more able to stimulate the type 1 IGF receptor and thus induce a higher level of activation of intracellular signaling, which is responsible for promoting cell proliferation and the inhibition of apoptosis.
