Peptide Class: Growth Factor Peptide / Insulin-Like Growth Factor Analog
OVERVIEW
IGF-1 LR3 (Insulin-Like Growth Factor-1 Long R3) is a synthetic analog of insulin-like growth factor-1 (IGF-1). It has been modified to increase its biological activity and stability, giving it a longer half-life compared to natural IGF-1.
IGF-1 LR3 is composed of 83 amino acids and includes structural modifications that reduce its binding to IGF binding proteins, allowing it to remain active for a longer period in research models.
In laboratory environments, IGF-1 LR3 is commonly studied for its potential role in cell growth, protein synthesis, metabolic regulation, and muscle development pathways.
POTENTIAL RESEARCH BENEFITS
IGF-1 LR3 is commonly studied for its potential role in:
Cellular Growth & Development
Investigated for its influence on cell growth and cellular proliferation pathways.
Protein Synthesis
Studied for its potential role in supporting protein synthesis and muscle tissue development models.
Muscle Recovery Research
Frequently examined in models related to muscle repair and recovery processes.
Metabolic Regulation
IGF-1 signaling may influence glucose metabolism and energy utilization.
Tissue Regeneration
Researchers investigate its role in cellular regeneration and growth signaling pathways.
MECHANISM OF ACTION
IGF-1 LR3 works by binding to the IGF-1 receptor (IGF-1R), which activates cellular pathways involved in growth, metabolism, and protein synthesis.
Research suggests it may:
Stimulate cell growth and proliferation
Enhance protein synthesis pathways
Influence glucose metabolism and nutrient utilization
Support cellular repair and regeneration mechanisms
The LR3 modification helps extend its activity by reducing interaction with IGF binding proteins.

STORAGE:
To maintain product stability and quality:
Store the lyophilized peptide at -20°C for long-term storage.
Short-term storage may be maintained at 2–8°C (refrigerated).
Keep the vial dry, sealed, and protected from light.
Avoid repeated freeze–thaw cycles, as this may reduce peptide stability.
Once reconstituted, solutions should be stored refrigerated and used within a short timeframe according to laboratory protocols.
For Research Use Only
