IGF-1 LR3
Long-Acting IGF-1 Analog
IGF-1 LR3 (Long Arg3 IGF-1) is an 83-amino-acid analog of human Insulin-like Growth Factor 1 featuring an N-terminal extension and an Arg substitution at position 3. These modifications reduce IGFBP binding, extending circulating half-life roughly 12-15x versus native IGF-1. Widely used in cell-culture and preclinical studies of anabolic signaling. For laboratory research use only.
Activates the IGF-1 receptor (IGF-1R) tyrosine kinase, driving PI3K/Akt/mTOR and Ras/MAPK cascades that regulate protein synthesis, proliferation, and cell survival.
For Research Use Only. Sold for in vitro laboratory research. Not for human or veterinary consumption. By purchasing, you confirm you are 21+ and a qualified research professional.
