IGF-1 LR3 (Long R3 IGF-1) for Research
Technical Overview
IGF-1 LR3 (Long R3 IGF-1) is a modified analogue of insulin-like growth factor-1 (IGF-1), a naturally occurring peptide involved in cellular signaling and growth factor pathways. It is studied for its interaction with IGF-1 receptors and the molecular pathways associated with growth factor activity.
Research applications
- Growth factor signaling: interaction with IGF-related pathways and receptor activity in cellular models.
- Cellular regulation: cell communication, differentiation and biological responses.
- Protein synthesis pathways: molecular processes related to protein regulation and cellular activity.
- Structure and activity: how structural modifications influence peptide activity and receptor binding.
- Molecular biology: controlled studies of growth factor mechanisms.
Researchers examine IGF-1 LR3 in experimental models to explore growth factor biology, signal transduction and pathways associated with cell growth and differentiation, helping to advance understanding of IGF-related pathways and their role in cellular regulation.

Storage Instructions
Handling and Storage Tips:
- On arrival, store the sealed vial at −20 °C, protected from light and moisture.
- For short-term storage (days to weeks), refrigeration at 2–8 °C is acceptable.
- Lyophilized peptides tolerate room temperature for short periods, such as during shipping.
- Let the vial reach room temperature before opening, to avoid condensation.
- Once reconstituted, keep refrigerated at 2–8 °C and avoid repeated freeze–thaw cycles.
