Q: How should the peptide be stored after receiving it?
A: The freeze-dried powdered peptide can be transported at room temperature in vacuum packaging, while the dissolved peptide needs to be refrigerated at 2℃ - 8℃. For long-term storage, the freeze-dried powdered peptide should be stored in a sealed container with desiccant and placed at -20℃ or -80℃, which can minimize the degradation of the peptide to the greatest extent.
