Lyophilized (freeze-dried) peptides are significantly more stable than reconstituted solutions.

Recommended Storage Conditions

Best Practices

• Keep vials sealed until ready for use.
• Store protected from light exposure.
• Avoid repeated temperature fluctuations.
• Maintain in original packaging when possible.

3. Reconstitution Guidelines

Reconstitution should be performed using sterile laboratory technique.

Common Diluents

• Bacteriostatic water
• Sterile water for injection
• Appropriate research-grade diluent

General Procedure

1. Clean vial tops with alcohol prior to entry.
2. Slowly introduce diluent along the inside wall of the vial.
3. Do not shake vigorously.
4. Gently swirl or roll until fully dissolved.
5. Allow solution to settle before further handling.

Avoid:

• Aggressive shaking (may compromise peptide structure)
• Introducing excessive air bubbles
• Using non-sterile equipment

4. Storage After Reconstitution

Once reconstituted, peptides are more sensitive and require strict temperature control.

Refrigeration Required

• Store at 2–8°C (36–46°F)
• Do not freeze unless compound-specific stability data supports freezing
• Avoid repeated warming and cooling cycles

Stability Window

Stability varies by compound, but general research handling practice suggests:

• Use within 2–8 weeks when properly refrigerated
• Discard if:
  • Solution becomes cloudy
  • Visible particulates form
  • Color changes occur
  • Sterility is compromised

Always label reconstituted vials with:

• Date of reconstitution
• Diluent used
• Final concentration

5. Preventing Degradation

Peptides are sensitive to:

• Heat
• UV light
• Oxidation
• Microbial contamination
• Excessive agitation

Preservation Best Practices

• Minimize exposure to open air.
• Use a new sterile needle for each vial entry.
• Limit repeated punctures of the stopper.
• Consider aliquoting into sterile secondary vials for longer research protocols.
• Maintain consistent cold storage conditions.

6. Long-Term Freezer Storage

For extended preservation:

• Store at -20°C (-4°F) or colder.
• Avoid repeated freeze-thaw cycles.
• If necessary, aliquot prior to freezing to reduce degradation risk.

7. Transportation & Travel

When transporting peptides:

• Use insulated cold packaging.
• Avoid prolonged exposure to elevated temperatures.
• Do not leave in vehicles.
• Maintain cold-chain conditions whenever possible.
