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

"We have no reason to use any other antibody company at this point! We are very pleased with your work. We realize the difficulty in obtaining high quality phosphorylated antibodies so we desire to stick with NEP. Thank you for your work on this!"
