Proper storage of research peptides is essential to maintain their stability, purity, and integrity. Following these guidelines will help ensure optimal product quality for your research.
General Storage Principles
All peptides should be stored according to the following general principles:
Store in original sealed containers until ready for use
Protect from light, heat, and moisture
Avoid repeated freeze-thaw cycles
Label all containers with product name and date received
Keep away from incompatible materials
Store in a dedicated research refrigerator or freezer
Storage by Form
Lyophilized (Freeze-Dried) Peptides
Unopened lyophilized peptides are the most stable form and can be stored for extended periods.
Short-term storage (up to 6 months):
Temperature: 2-8°C (refrigerator)
Keep in original sealed vial
Protect from light and moisture
Long-term storage (6+ months):
Temperature: -20°C to -80°C (freezer)
Use desiccant packs to control moisture
Store in airtight containers
Reconstituted Peptides
Once reconstituted with bacteriostatic water or other solvents, peptides have reduced stability.
Storage requirements:
Temperature: 2-8°C (refrigerator) - REQUIRED
Use within 14-30 days (varies by peptide)
Store in sterile, sealed vials
Protect from light using amber vials or foil wrap
Never freeze reconstituted peptides
Minimize exposure to room temperature
Temperature Guidelines
Refrigerator
2-8°C
For reconstituted peptides and short-term storage of lyophilized products
Freezer
-20°C
For long-term storage of lyophilized peptides (6-12 months)
Deep Freezer
-80°C
For extended long-term storage (12+ months) and maximum stability
Upon Receipt
When you receive your peptides, take the following steps immediately:
1
Inspect the package: Check for any signs of damage or temperature compromise. If ice packs have completely melted, contact us immediately.
2
Transfer to proper storage: Immediately place peptides in appropriate storage conditions (refrigerator or freezer) as indicated on the product label.
3
Record information: Note the date received, lot number, and expiration date for your records.
4
Review storage requirements: Check the product-specific storage instructions included with your order.
Reconstitution Best Practices
When reconstituting lyophilized peptides:
Use bacteriostatic water or sterile water as specified
Allow vial to reach room temperature before reconstitution
Add solvent slowly down the side of the vial
Gently swirl (do not shake vigorously)
Allow to dissolve completely before use
Use sterile technique throughout the process
Store reconstituted solution immediately in refrigerator
Common Storage Mistakes to Avoid
Do NOT:
✗ Store peptides in household refrigerators with food
✗ Expose to direct sunlight or UV light
✗ Leave at room temperature for extended periods
✗ Freeze reconstituted peptides
✗ Repeatedly freeze and thaw lyophilized peptides
✗ Store near heat sources or in humid environments
✗ Use peptides past their expiration date
✗ Mix different peptides in the same vial
Signs of Degradation
Discard peptides if you observe any of the following:
Change in color or appearance
Cloudiness or precipitation in solution
Unusual odor
Visible contamination or particles
Broken or compromised seal
Past expiration date
Product-Specific Storage
Some peptides have unique storage requirements. Always refer to the product-specific information provided with your order. Common variations include:
Light-sensitive peptides: Store in amber vials or wrap in aluminum foil
Moisture-sensitive peptides: Use desiccant packs and airtight containers
Temperature-critical peptides: May require -80°C storage
Short-lived peptides: Use within specified timeframe after reconstitution
Laboratory Storage Equipment
For optimal peptide storage, we recommend:
Dedicated laboratory refrigerator with temperature monitoring
Frost-free freezer for long-term storage
Temperature data logger for compliance documentation
Backup power supply for critical storage units
Organized storage system with clear labeling
Shipping & Transport
If you need to transport peptides:
Use insulated containers with ice packs
Minimize transport time
Protect from temperature fluctuations
Document temperature during transport
Transfer to proper storage immediately upon arrival
Summer Shipping Notice
During hot weather months, we strongly recommend selecting expedited shipping to minimize exposure to high temperatures. Standard shipping may result in compromised product quality during extreme heat.
