Temperature

Lyophilized peptides are naturally stable, but temperature control helps preserve their structure
over time.

• Short-term storage (weeks to several months): Refrigeration at ≤ 4°C (39°F) is typically sufficient.
• Room-temperature stability: Lyophilized materials generally remain stable at ambient temperatures for several weeks when kept dry and protected.
• Long-term storage: For extended preservation, store peptides in a –80°C (–112°F) freezer tominimize degradation.

Moisture Control

Moisture is one of the primary factors that can compromise peptide integrity.

• Keep vials tightly sealed.
• Use airtight containers or include desiccants to limit humidity exposure.
• Avoid opening vials in high-humidity environments.

Light Protection

• Exposure to light—especially UV—can degrade certain peptides.
• Store vials in opaque containers or wrap them in foil.
• Keep them away from direct light sources during handling.

Clean Handling To support sample integrity:

• Use clean, sterile tools when accessing peptide vials.
• Minimize unnecessary exposure to open air
• Avoid touching stoppers or vial interiors.

Avoid Freeze–Thaw Cycles

• Repeated temperature cycling can impact peptide stability.
• Divide materials into aliquots so only the required amount is thawed at a time.
• Keep remaining aliquots frozen until needed.

Freezer Considerations for long-term storage:

• Use a freezer that maintains a consistent, stable temperature.
• Avoid units with frequent defrost cycles or temperature fluctuations.
• Note Individual peptides may have unique storage considerations. Always refer to the specificationsprovided for each material to ensure optimal handling.
