IGF-1 LR3: The Long-Acting Growth-Factor Analog in Cell Research
A modified IGF-1 analog widely used as a cell-culture research reagent.
IGF-1 LR3 is a modified, long-acting analog of insulin-like growth factor 1, widely used as a reagent in cell-culture and growth-signaling research.
What IGF-1 LR3 is
IGF-1 LR3 (Long R3 IGF-1) is an engineered version of IGF-1 with amino-acid modifications that extend its activity and reduce binding to carrier proteins — useful properties in the lab.
Why it’s studied
It is commonly used in cell-culture research to study proliferation, differentiation, and growth-factor signaling pathways.
Research-reagent standards
Because it is used quantitatively in experiments, verified purity and identity are critical — per-batch COAs and third-party HPLC testing.
Research-grade IGF-1 LR3 from Prestige Sciences — ≥99% purity by HPLC, a Certificate of Analysis on every batch, U.S.-shipped with insured delivery.
