IGF-1 LR3 is supplied as a lyophilized reference standard for laboratory research use only. Each lot is released against HPLC purity and mass spectrometry identity testing, with the certificate of analysis matched to the lot code printed on the vial.
- The R3 substitution and 13-residue extension lower binding-protein affinity, which is why this analogue is used in cell-culture models rather than native IGF-1.
- Handle at 1 mg scale: reconstitute the whole vial and aliquot rather than repeatedly piercing it.

Storage
Store the sealed lyophilized vial at -20 °C, protected from light. Once reconstituted, keep refrigerated at 2–8 °C and use within the window defined by your protocol.
Handling
Allow the vial to reach room temperature before opening. Reconstitute slowly against the glass wall with bacteriostatic or sterile water; do not shake. Record the lot code in your laboratory notes.
Certificate of analysis
Every lot ships with a matched certificate: HPLC chromatogram, mass spectrometry identity confirmation, water content and the independent laboratory that released it.
Questions about IGF-1 LR3
- What is IGF-1 LR3?
- IGF-1 LR3 is a lyophilized peptide reference standard supplied at 1 mg per vial and released at 98.7% purity by reverse-phase HPLC. It is sold for in-vitro laboratory research only and is not a medicine.
- How is the purity of IGF-1 LR3 tested?
- Purity is measured by reverse-phase HPLC and identity is confirmed by electrospray mass spectrometry against the expected molecular mass. The method, gradient and detection wavelength are named on the certificate.
- Is a certificate of analysis available for IGF-1 LR3?
- Yes. Every lot ships with a matched certificate of analysis carrying the HPLC chromatogram, mass spectrometry identity confirmation and water content, searchable by the lot code printed on the vial.
- How should IGF-1 LR3 be stored?
- Store the sealed lyophilized vial at -20 °C protected from light. After reconstitution, keep the solution at 2–8 °C and avoid repeated freeze-thaw cycles.
- How is IGF-1 LR3 shipped?
- Cleared orders are packed cold-stable and handed to a tracked carrier within 24 hours on business days. Lyophilized material tolerates normal transit temperatures; refrigerate on arrival.
- Which solvent is used to reconstitute IGF-1 LR3?
- Bacteriostatic or sterile water, added slowly down the inside wall of the vial. Our TPS-190 Reconstitution Solution (30 mL bacteriostatic water) is compatible with every vial in the catalog.
