Peptides are delicate. Correct storage protects their integrity from the moment they arrive to long after reconstitution.
Before reconstitution (lyophilized)
Keep the freeze-dried powder frozen at around −20 °C, away from light and moisture. In this state peptides are stable for extended periods.
After reconstitution
- Refrigerate at 2–8 °C.
- Protect from light.
- Avoid freeze–thaw cycles — they degrade peptide structure.
- Never shake; swirl gently.
- Use within the period appropriate to your compound (commonly up to ~4 weeks).
Good practice
Label every vial with date and concentration, keep your workspace clean, and use sterile technique at every step.
