Peptide Storage Guidelines: Best Practices for Research Stability

At Ceritide Research, we provide high-purity peptides for laboratory and scientific research. Proper storage preserves peptide integrity and supports reliable experimental results.

Storage Guidelines for Lyophilized (Powder) Peptides

• Long-Term Storage: Keep at -20°C (-4°F) or lower (ideally -80°C / -112°F) for multi-year stability.
• Short-Term Storage: Refrigerate at 2–8°C (36–46°F) for weeks to a few months. Minimize room temperature exposure.
• Best Practices: Store in airtight vials with desiccants. Allow vials to reach room temperature in a desiccator before opening. Protect from light and moisture. Aliquot to reduce freeze-thaw cycles.

Storage Guidelines for Reconstituted Peptide Solutions

Once dissolved, peptides are less stable and should be used promptly:

• Recommended Temperature: Store at 2–8°C (36–46°F) (refrigerator) for short-term use, typically up to 1–4 weeks depending on the sequence and buffer.
• Longer-Term Solution Storage: Aliquot and freeze at -20°C (-4°F) or lower. Avoid storing solutions long-term when possible.
• Best Practices: Use sterile techniques, bacteriostatic water or research-grade buffers, and minimize exposure to air and light. Prevent repeated freeze-thaw cycles.
