This product is provided in freeze-dried form and is recommended to be stored in an environment of ≤ -20 ° C (-4 ° F) for a long time to avoid repeated freeze-thaw cycles and maintain stability for several years. Packaging and storage can effectively reduce freeze-thaw damage. If reconstructed into a solution, it should be strictly refrigerated at ≤ -20 ° C (-4 ° F), and the shelf life should be shortened to 3-4 months; If stored at ultra-low temperatures of -80 ° C (-112 ° F), the stability can be extended to 12 months. The peptide activity is prone to decay after reconstruction, and it is recommended to prepare and use it as needed. For long-term storage, freeze-drying or ultra-low temperature solutions are preferred. The actual effect may vary depending on the operating conditions, and it is recommended to conduct activity verification before use.
