IGF-1 LR3 1mg

IGF‑1 LR3 — Overview

IGF‑1 LR3 (Long Arg3 Insulin‑Like Growth Factor‑1) is a synthetic analog of naturally occurring IGF‑1. It is engineered with specific modifications—most notably the substitution of arginine at position 3 and an extended amino‑terminal sequence—to enhance stability, bioavailability, and receptor‑binding characteristics. Because of these properties, IGF‑1 LR3 is frequently used in research focused on cellular growth pathways, protein signaling, and metabolic regulation.

Background & Research Interest

IGF‑1 LR3 is commonly studied in laboratory environments exploring:

• IGF‑1 receptor signaling
• Cellular growth and differentiation pathways
• Protein synthesis mechanisms
• Peptide engineering and analog design
• Interactions between IGF‑1 and insulin‑related pathways

Its extended half‑life compared to native IGF‑1 makes it a useful model for studying long‑acting growth‑factor analogs.
