Product details
IGF-1 LR3
IGF-1 LR3 is a modified analogue of insulin-like growth factor-1 investigated in molecular and cellular research. Its extended structure has made it of interest for studies examining IGF-1 receptor signaling, PI3K-AKT pathways, cellular proliferation, metabolism, and growth-related mechanisms. Research involving IGF-1 LR3 can help investigate how altered peptide structure influences receptor interactions and downstream cellular signaling.
