Peptide Storage

Storing research peptides properly is crucial to maintain their stability and integrity. Here's a brief guide:


1. Temperature: Keep peptides in a cool and dry environment.  If the peptides will be used immediately, or in the next several months, short-term refrigeration under 4C (39F) is generally adequate. Lyophilized peptides tend to be stable at room temperatures for several weeks or more, so if they will be utilized within months such storage is generally sufficient. For longer term storage, it is best to store peptides in a freezer at -80C (-112F). 

 2. Moisture: Prevent exposure to moisture as it can degrade peptides. Use airtight containers or containers with desiccants to absorb any moisture that may be present.

 3. Light: Protect peptides from light exposure, especially UV light, as it can cause degradation. Store them in opaque containers or wrap them in aluminum foil.

 4. Contamination: Ensure proper handling to prevent contamination. Use clean and sterile equipment when handling peptides.

 5. Avoid freeze-thaw cycles: Frequent temperature fluctuations can lead to peptide degradation. Divide the peptides into aliquots, so you only thaw what you need without repeatedly exposing the entire sample to temperature changes.

 6. Freezer selection: If you're using a freezer for storage, choose one that maintains a stable and constant temperature, as fluctuations can negatively impact peptide stability.


Remember that each peptide may have specific storage requirements, so always refer to the manufacturer's guidelines or consult with an expert for the best storage practices for your particular peptides.
