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.

Testimonials

"THANKS AGAIN for all the intellectual support that NEP has provided to us over the last year. My colleagues have been overwhelmingly impressed with the quality of service and level of thought that you have put into researching and thinking about our particular peptide and antibody production needs. The level of scholarship went well beyond what we expected from any peptide and antibody company, and was crucial in shaping our decisions. It has truly been a pleasure corresponding with you."
