Overview

IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) is a synthetic analog of IGF-1 engineered for enhanced stability, reduced binding to IGF-binding proteins, and prolonged biological activity. It retains the growth-promoting and metabolic functions of native IGF-1 but exhibits greater receptor availability and longer half-life, making it useful in experimental research.

Key Features

  • Peptide Length: 70 amino acids with N-terminal Arg modification (LR3)

  • Enhanced Stability: Resistant to proteolytic degradation

  • Potency: Increased activation of IGF-1 receptor pathways due to reduced binding to IGF-binding proteins

  • Water Solubility: Linear peptide suitable for laboratory use

Applications

  • Studying cellular proliferation and growth signaling pathways

  • Research on muscle, cartilage, and bone regeneration

  • Investigation of anti-apoptotic mechanisms and tissue repair

  • Metabolic studies including glucose uptake and lipid metabolism


Summary

IGF-1 LR3 is a long-acting IGF-1 analog with enhanced bioactivity and stability, widely used in research to explore growth factor signaling, tissue regeneration, and metabolic effects, strictly for experimental or in vitro applications.

Biochemical
Characteristics

Storage

1️⃣ Lyophilized (Powder) Form

  • Temperature: Store refrigerated at 2–8 °C (36–46 °F) for short-term use

  • Long-Term Storage: Freeze at −20 °C or below to preserve stability

  • Light Protection: Keep protected from direct light

  • Moisture Protection: Maintain in original sealed vial

  • Shelf Life: Typically 12–24 months when stored properly


2️⃣ Reconstituted Solution

  • Diluent: Sterile water or bacteriostatic water

  • Temperature: Refrigerate at 2–8 °C

  • Use Period: Recommended within 7–14 days

  • Handling: Gently swirl to dissolve; avoid vigorous shaking

  • Do NOT freeze after reconstitution


3️⃣ General Precautions

  • Inspect solution before use: should be clear, colorless, and free of particulates

  • Discard if cloudy, discolored, or precipitated

  • Use sterile technique during reconstitution and experimental handling

  • Protect from heat, light, and mechanical agitation to maintain peptide integrity


Summary

IGF-1 LR3 is most stable as a lyophilized powder stored refrigerated or frozen. Once reconstituted, it should be kept cold, used promptly, and protected from light and agitation to preserve biological activity for laboratory and research applications.
