Best Practices For Storing Peptides
Proper storage practices are crucial for maintaining the purity of peptides and ensuring accurate laboratory results. Following these best practices can protect against contamination, oxidation, and degradation that may compromise the quality of the peptides and the success of your experiments.
Upon receiving the peptides, store them in a cold and light-free environment. If you plan to use the peptides for your research immediately or within a few days, weeks, or months, short-term then you can refrigerate it under 4°C (39°F). Peptides stored at this temperature can last 1-2 years (Unmixed). Lyophilized peptides can often remain stable at room temperature for several weeks or longer, making room-temperature storage suitable for short-term use (away from sunlight).
For longer-term storage, especially over several years, it is best to keep peptides in a freezer. Freezing the peptides ensures their stability and preserves their quality over extended periods.
To maintain the peptides' stability, it is essential to avoid repeated freeze-thaw cycles. Each cycle can increase the risk of degradation, so minimizing freezing and thawing is crucial for maintaining peptides' stability.
Finally, frost-free freezers should be avoided for peptide storage, as they can cause significant temperature fluctuations during defrosting cycles affecting it's stability. Opt for conventional freezers to ensure consistent and reliable storage conditions. By adhering to these best practices, you can extend the lifespan of your peptides and optimize the success of your experiments.
