Stability is material-specific
There is no universal storage condition for every peptide or preparation. Stability can depend on sequence, formulation, physical state, container, temperature, light exposure, moisture, time, and handling history. Product-specific documentation should take priority over general guidance.
Control the environment
Laboratory materials should be protected from conditions identified as risks in their documentation. Common controls include limiting unnecessary light, heat, moisture, contamination, and repeated temperature changes.
- Use suitable, clearly labeled containers.
- Minimize unnecessary handling and environmental exposure.
- Keep storage equipment monitored and maintained.
Maintain traceable records
Record receipt, lot information, storage location, relevant temperature history, transfers, and disposition according to the laboratory's procedures. Good records help researchers evaluate whether an unexpected result could be related to handling history.
Respond to an excursion
If material experiences an undocumented or out-of-range condition, isolate it as appropriate and review product-specific information before deciding whether it remains suitable for an experiment. Appearance alone is not a complete stability assessment.
