How to Store Research Peptides Correctly

Synthetic peptides are susceptible to degradation through oxidation, hydrolysis, aggregation, and microbial contamination. Each of these is accelerated by heat, moisture, and light exposure. A compound that arrives at 98% purity can degrade significantly if stored incorrectly.

• Temperature: -20°C. Long-term storage at -80°C extends shelf life further for compounds that will not be used within six months. Avoid repeated freeze-thaw cycles.
• Humidity: Store in a desiccated environment. Silica gel desiccant packets inside the storage container are standard practice. Lyophilised peptides are hygroscopic and will absorb atmospheric moisture if left unsealed.
• Light: Store away from direct light. Amber vials or opaque storage containers are recommended.
• Atmosphere: Some peptides benefit from storage under inert atmosphere. Alluvi Labs dispatches compounds sealed under inert atmosphere as standard.

Peptides should remain lyophilised until immediately before experimental use. When reconstituting:

• Use bacteriostatic water or sterile phosphate-buffered saline
• Allow the vial to reach room temperature before opening
• Add solvent slowly down the side of the vial
• Mix gently by rolling — do not vortex
• Once reconstituted, use within your experimental protocol timeframe

Research peptides should be transported on ice with appropriate cold chain packaging. Alluvi Labs dispatches all compounds cold within 48 hours using temperature-controlled packaging.

Lot-specific documentation allows researchers to correlate experimental results with specific production batches. Always retain CoA documentation alongside experimental records.
