IGF-1 LR3 Peptide Characteristics

Handling & Storage Guidelines

Proper handling of IGF-1 LR3 is essential to maintain structural integrity and ensure reproducible laboratory results. As a recombinant growth factor analog supplied in lyophilized form, it should be stored and reconstituted under controlled research conditions.

• Storage (Lyophilized): Store unopened vials refrigerated at 36–46°F (2–8°C). For extended storage, freezing at or below 0°F (−18°C) is recommended. Protect from direct light, heat, and moisture.
• Reconstitution: Reconstitute using sterile laboratory-grade water or bacteriostatic water under aseptic conditions. Introduce diluent slowly and avoid agitation; gently swirl until fully dissolved. For the best stability, purity, and consistent results, get bacteriostatic water with your IGF-1 LR3 order.
• Aliquoting & Freeze–Thaw: If repeated use is anticipated, aliquot into sterile microtubes to minimize repeated freeze–thaw cycles, which may compromise structural stability.
• Working Solution Storage: Store reconstituted solutions at 36–46°F (2–8°C) for short-term use. For longer-term storage, aliquots may be frozen at or below 0°F (−18°C) according to institutional guidelines.
• Laboratory Compliance: Handle with appropriate personal protective equipment and in accordance with institutional biosafety protocols. This material is designated strictly for research use only.

COA / Quality Assurance

Each lot of IGF-1 LR3 is supported by a lot-specific Certificate of Analysis (COA) to ensure transparency, traceability, and research reproducibility. Eternal Peptides works with independent third-party analytical laboratories, including Janoshik, to provide objective verification of identity and purity standards.

COAs are generated for every production batch and typically include:

• Peptide Identity: Confirmation via high-performance liquid chromatography (HPLC) and/or mass spectrometry to verify molecular weight and structural conformity.
• Purity Analysis: Quantitative purity assessment, commonly ≥99%, based on chromatographic profiling.
• Sterility Testing (where applicable): Evaluation for microbial contamination depending on product format and handling expectations.
• Endotoxin Levels: Analytical measurement to support use in sensitive laboratory environments.
• Storage & Handling Guidance: Recommended conditions to preserve peptide stability and integrity.

All COAs are lot-specific, fully traceable, and accessible through the Lab Tests page to assist with documentation, audit requirements, and experimental consistency.
