Unless otherwise noted on the product's Certificate of Analysis, lyophilized (freeze-dried) peptides should be stored at -20°C for long-term stability and are generally stable at 2-8°C for shorter periods. Once reconstituted in a laboratory setting, solutions should be kept refrigerated and used within the timeframe indicated by your own stability testing or standard peptide-handling protocols. Avoid repeated freeze-thaw cycles and direct light exposure, which can degrade peptide integrity.

Each COA lists the batch number (a unique identifier for that production lot), the measured purity percentage (typically via HPLC), the analytical test method used, the date testing was completed, and the name of the testing laboratory. You can look up the COA for any product on our /coa page by selecting the product from the dropdown. Always cross-reference the batch number on your product's label with the batch number on the COA before use in your research protocol.
