How to Store Peptides for Maximum Stability

Improper storage can compromise peptide integrity—and your research. Here’s how to store peptides properly for both short- and long-term use.

Storing Lyophilized Peptides (Freeze-Dried)

• Short-Term (1–2 weeks): Store in a cool, dry place away from sunlight
• Long-Term: Keep sealed vials stored at -20°C for maximum stability

Storing Reconstituted Peptides

• Refrigerate at 2–8°C
• Use within a few weeks for best results
• Avoid repeated freeze-thaw cycles

Pro Tips

• Always keep vials sealed until needed
• Label reconstituted solutions with preparation date and concentration

Final Thoughts

Proper storage preserves peptide stability and ensures reproducible results.
