Great peptide storage information. Lerner. Peptides are provided as lyophilized product that should be stored as dry powder at -20°C to -70°C in a desiccator, if possible. After lyophilization, peptides retain significant amounts of water. Peptides are slowly degraded particularly the cysteine-containing peptides are oxidized over time at -20°C. - [Read Peptide Storage Information]
