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 & Intended Use

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.

Answers

Frequently Asked Questions

Is IGF-1 LR3 third-party tested?

Yes. Each lot is tested by Bioviridian, an independent HPLC-MS laboratory, for identity (mass spectrometry), purity (RP-HPLC), content and endotoxin, and the Certificate of Analysis is published for that lot.

Can I see the Certificate of Analysis before buying?

Yes. Download it from the Documents section above, or search the lot number in our COA library.

What does 'Research Use Only' mean?

Products are supplied only for laboratory research. They are not drugs, foods, supplements or cosmetics and are not for human or veterinary use.

How is it shipped and stored?

Cold-packed with tracking, same day on orders by 2 PM ET. Store lyophilized vials at −20 °C on arrival.
