Peptide Storage and Stability in the Laboratory

Handling lyophilised peptides

Lyophilised peptides are stable at room temperature for short shipping windows but are stored at −20 °C for long-term integrity in laboratory settings.

Stability factors studied in the literature

Published stability work on peptide reference materials focuses on solvent choice, temperature, and container handling. Solutions prepared for analytical work are typically held at 2–8 °C and used within the validated stability window for the assay in question.

Avoiding degradation

• Limit freeze-thaw cycles
• Protect from light
• Keep vials upright and sealed
