How should I store and use lyophilized peptides?

1.Peptides should be stored at -20°C for maximum stability. They should not be stored in frost-free freezers as variations in moisture and temperature may affect product stability.

2.Because peptides are often hygroscopic, they can absorb water, which may decrease stability and reduce the overall peptide content. To minimize this, allow peptide samples to equilibrate to room temperature in a desiccator for at least 1 hour prior to opening the vial and weighing the peptides.

3.Weigh out peptides quickly and reseal bottle tightly
