How to Store Lyophilized Peptides Correctly

If you purchase research peptides, proper storage is essential to maintain their stability, purity, and research quality. Incorrect storage conditions can accelerate degradation and reduce the integrity of lyophilized peptides.

## Store Before Reconstitution

Lyophilized peptides should be stored in a freezer at approximately -20°C (-4°F). Keep vials sealed, dry, and protected from light and moisture. Avoid frequent temperature changes.

## After Reconstitution

Once bacteriostatic water or another research solvent has been added, store the peptide in a refrigerator between 2°C and 8°C (36–46°F).

Avoid repeated freeze-thaw cycles, as they may reduce peptide stability.

## Protect From Moisture and Light

Always keep the vial tightly closed when not in use. Exposure to humidity, heat, or direct sunlight may negatively affect long-term stability.

## Recommended Storage Guidelines

– Lyophilized peptide: Freezer (-20°C)
– Reconstituted peptide: Refrigerator (2–8°C)
– Protect from heat, moisture, and sunlight
– Keep containers tightly sealed
– Minimize freeze-thaw cycles

## Conclusion

Proper storage helps preserve the integrity of research peptides and ensures consistent laboratory research quality. Always follow recommended storage practices and refer to product-specific documentation when available.
