STORAGE

Storage Instructions

All products are prepared via a sophisticated lyophilization (freeze-drying) process, which ensures optimal stability during transit for approximately 3–4 months.

Once the peptide is reconstituted with bacteriostatic water, the resulting solution must be stored under refrigeration to preserve its activity and remains stable for a period of up to 30 days.

Lyophilization, or cryodesiccation, is a specialized dehydration process that involves freezing the peptide and subjecting it to a low-pressure environment. This carefully controlled process drives the water to sublimate (direct transition from solid to gas), yielding a white crystalline structure known as a lyophilized peptide. This stable powder can be maintained at room temperature until the point of reconstitution with bacteriostatic water.

For long-term preservation—lasting several months up to multiple years—storage in a freezer at -80°C (-112°F) is the established protocol. Freezing at this ultralow temperature is essential for maintaining the peptide’s native structural integrity and ensuring its stability over the longest possible duration.

Upon receiving the product, peptides must be kept cool and fully shielded from light. For short-term use (ranging from a few days to a few months), refrigeration below 4°C (39°F) is sufficient. Lyophilized peptides typically maintain stability at room temperature for several weeks, making this an acceptable method for short holding periods before experimental use.

Best Practices For Storing Peptides

Implementing correct storage procedures for peptides is critical for ensuring the accuracy, validity, and reproducibility of all laboratory results. Following these protocols minimizes the risk of contamination, oxidation, and degradation, thereby guaranteeing that the peptides remain stable and fully functional for extended periods. While susceptibility to breakdown varies between different peptides, strict adherence to best practices significantly extends their operational lifespan.

Upon receipt, peptides should be kept cool and protected from light. For short-term use, refrigeration below 4°C (39°F) is adequate. Lyophilized peptides are generally stable at room temperature for several weeks, making this acceptable for brief storage.

For long-term preservation over several months or years, peptides should be stored in a freezer at -80°C (-112°F). This provides the optimal stability and protection against structural degradation.

It is absolutely vital to minimize freeze-thaw cycles, as repeated temperature fluctuations are known to accelerate degradation. Furthermore, frost-free freezers must be avoided because their automatic defrosting cycles induce temperature variations that compromise peptide stability.

Preventing Oxidation and Moisture Contamination

It is essential to diligently protect peptides from exposure to both ambient air and moisture, as both are significant factors that compromise stability. Moisture contamination is a particular risk when removing peptides from frozen storage. To prevent condensation from forming on the cold peptide or inside its container, always allow the vial to fully reach room temperature before opening it.

Minimizing air exposure is equally paramount. The peptide container should remain closed as much as possible, and it must be promptly resealed after the necessary amount has been removed. Storing the remaining peptide under a dry, inert gas (such as nitrogen or argon) can provide an additional layer of protection against oxidation. Peptides containing the sensitive residues cysteine (C), methionine (M), or tryptophan (W) are highly prone to air oxidation and require meticulous handling.

To ensure long-term stability, frequent thawing and refreezing must be strictly avoided. The most effective practical approach is to divide the total peptide quantity into smaller, single-use aliquots. This method prevents repeated exposure to air and temperature changes, thereby maximizing the peptide’s structural integrity over time.

Storing Peptides In Solution

Peptide solutions have a notably shorter shelf life compared to the lyophilized form and are far more susceptible to potential bacterial degradation. Peptides containing residues such as cysteine (Cys), methionine (Met), tryptophan (Trp), aspartic acid (Asp), glutamine (Gln), or N-terminal glutamic acid (Glu) are known to degrade more quickly when kept in a solution state.

If storage in solution is necessary for experimental workflow, it is strongly recommended to use sterile buffers with the pH maintained between 5 and 6. The solution should be aliquoted immediately to minimize the number of freeze-thaw cycles. When refrigerated at 4°C (39°F), most peptide solutions remain stable for up to 30 days. However, peptides with documented stability issues should be kept frozen when not in immediate use to best preserve their structural integrity.

Peptide Storage Containers

The containers chosen for peptide storage must be clean, transparent, durable, and chemically inert. They should be appropriately sized to the quantity of peptide being stored, ensuring minimal excess air space. Both glass and plastic vials are suitable. Plastic options are typically fabricated from polystyrene or polypropylene. Polystyrene offers high clarity but limited chemical resistance, while polypropylene provides better chemical resistance but is often translucent.

High-quality glass vials are generally preferred as they offer the optimal combination of clarity, stability, and chemical inertness for peptide storage. However, peptides are commonly shipped in plastic containers to mitigate the risk of breakage during transport. Peptides can be safely transferred between glass and plastic vials to suit specific long-term storage or handling requirements.

Peptide Storage Guidelines: General Tips

Adherence to these fundamental best practices is essential for maintaining peptide stability and preventing degradation:

• Store peptides in a cold, dry, and dark environment.
• Avoid repeated freeze-thaw cycles to prevent structural damage.
• Minimize exposure to air to reduce the risk of oxidation.
• Protect peptides from light, which can induce structural changes.
• Do not store peptides in solution long term; keep them lyophilized whenever possible.
• Aliquot peptides based on experimental needs to prevent unnecessary handling and exposure.
