Storage Recommendations

Proper storage of a peptide can prevent bacterial degradation, secondary structure formation, oxidation, and other potential degradation for several years.

Peptides are most stable in their lyophilized form at -20° C or colder in a sealed container containing desiccant.  If peptide must be stored in solution, ensure pH is in the 3-6 range and then aliquot peptide into usable sizes to prevent damage from multiple freeze/thaw cycles.  Cysteine (C), methionine (M), tryptophan (W), asparagine (N), and glutamine (Q) are most sensitive to degradation in solution.
