Storing and handling lyophilised research peptides

August 12, 2026 · 4 min read

Lyophilised peptides are stable materials when they are kept dry and cold, and considerably less stable once that changes. These notes cover general laboratory handling of reference material and are not protocol guidance.

Temperature

Store sealed lyophilised vials at -20°C. Short periods at room temperature during shipping are normal and accounted for in our packaging, but repeated warming shortens the useful life of the material.

Reconstituted material belongs in a refrigerator at 2°C to 8°C and should be treated as having a much shorter working life than the sealed powder.

Light and moisture

Keep vials in their original packaging, away from direct light. Allow a cold vial to equilibrate to room temperature before opening, otherwise atmospheric moisture condenses onto the powder as soon as the seal is broken.

Freeze-thaw cycles

Each freeze-thaw cycle degrades a portion of the material. Aliquoting reconstituted solution into single-use volumes avoids repeatedly cycling an entire stock.

Documentation

Record the lot number and receipt date alongside your own storage log. If a result later looks anomalous, the batch-matched Certificate of Analysis gives you a reference point for what the material was at release.
