IGF-1 LR3 (Long R3 IGF-1)
What Is IGF-1 LR3 (Long R3 IGF-1) Used For in Laboratory Research?
IGF-1 LR3 is a synthetic 83-amino-acid recombinant analog of human Insulin-Like Growth Factor-1 with an Arg substitution at position 3 and a 13-amino-acid N-terminal extension. These modifications dramatically reduce binding affinity to inhibitory IGF Binding Proteins (IGFBPs), prolonging in-vitro receptor bioavailability and biological half-life from 20 minutes to over 20 hours.
Key Researched Benefits & Biological Mechanisms
Peer-reviewed in-vitro and animal literature highlights the following key biochemical outcomes:
Potent activation of the IGF-1R tyrosine kinase receptor triggering downstream Akt/mTOR signaling.
Stimulation of skeletal myoblast satellite cell hyperplasia and amino acid transport.
Overcoming IGFBP inhibitory binding to maintain sustained bio-active signaling in cell culture.
Upregulation of protein synthesis pathways and inhibition of ubiquitin-proteasome protein breakdown.
