Lyophilized (Unmixed)

● Short term - Lyophilized peptides will remain stable at room temperature for 30-60 days. However, upon receipt all peptides should be stored in the refrigerator (under 4C (39F) for maximum stability and longevity. Peptides stored at this temperature can last 1-2 years.
● Long term - If you are not going to use the peptides withing 1-2 months it is preferable to store the peptides in a freezer at -18C (0F). Peptides stored at this temperature can last 2-3 years. Even more preferable for long term storage is freezing at -80C (-112F) in order to preserve the peptides stability long term.

Reconstituted (Mixed)

● Short term - Peptide solutions generally remain stable up to 30 days when stored in the refrigerator at 4C (39F) depending on the length of the peptide sequence and its inherent instability factors.
● Long term - If peptides absolutely must be stored in solution, sterile buffers at pH 5-6 should be used if possible, and the peptide solution should be separated into aliquots to avoid repeated freezing and thawing. Freezing at -80C (-112F) is optimal in order to preserve the peptides stability.
