To prevent peptides from absorbing moisture from the air, the following measures can be taken:
Freeze dried powder storage: The peptide is made into a freeze-dried powder form and sealed in packaging. In this state, peptides can be transported stably at room temperature, but for long-term storage, it is recommended to place them in a sealed container containing a desiccant and store them at -20 ° C. The storage condition at -80 ° C is more effective.
Equilibration to room temperature: Before opening the packaging and weighing, be sure to equilibrate the peptide in a desiccator to room temperature. Due to the hygroscopicity of peptides, opening the lid directly before reaching room temperature may cause coagulation, which can reduce the stability of peptide products.
Quick operation: When extracting peptides for use, complete weighing and other operations as quickly as possible, and immediately reseal the remaining peptides and continue to store them in a temperature environment of -20 ° C or lower.
Through the above methods, the risk of peptides absorbing moisture due to exposure to air can be effectively reduced, thereby extending their shelf life.
