1. What Is Lyophilisation?
Lyophilisation, or freeze-drying, is a process that removes water from a substance by freezing it and then reducing the surrounding pressure to allow the frozen water to sublimate directly into vapour.
2. Stability and Shelf Life
Peptides in liquid form can degrade relatively quickly due to hydrolysis and other chemical reactions. Lyophilisation significantly increases stability, allowing peptides to be stored for extended periods without losing integrity.
3. Protection from Degradation
Removing water reduces the risk of microbial growth and chemical breakdown. This is especially important for delicate peptide structures, which can be sensitive to environmental conditions such as temperature and pH.
4. Ease of Storage and Transport
Lyophilised peptides are lightweight, stable, and easier to transport. They typically require less stringent storage conditions compared to liquid formulations, making them more practical for distribution and handling.
5. Reconstitution for Use
Before use in research, lyophilised peptides must be reconstituted with an appropriate solvent. This allows researchers to prepare precise concentrations while maintaining the peptide’s stability until needed.
