Peptide Storage Guidelines

General Storage Rules

Proper storage is essential for maintaining peptide integrity for research purposes.

Lyophilized (Powder) Peptides

  • Temperature: Store at -20°C to -80°C (freezer)
  • Light: Keep away from direct light
  • Moisture: Store in a dry environment
  • Shelf Life: Up to 2 years when stored properly

Reconstituted Peptides

  • Temperature: Store at 2-8°C (refrigerator)
  • Duration: Use within 30 days of reconstitution
  • Container: Keep in original vial, sealed

Important Tips

  1. Avoid repeated freeze-thaw cycles
  2. Allow vials to reach room temperature before opening
  3. Use bacteriostatic water for reconstitution
  4. Label reconstituted vials with date

Signs of Degradation

  • Unusual color changes
  • Cloudiness after reconstitution
  • Unusual odor

Note: These are general guidelines for research purposes. Always follow your laboratory's specific protocols.
