The Formula
Formulation
Stability
General peptide stability is significantly influenced by pH. Dimeric peptides, including Heptapeptide-40 Dimer, may exhibit maximal stability around a neutral pH of 7, with potential dissociation and reduced stability observed at lower pH values, specifically below pH 5. Dimer formation can also arise as an impurity concern, particularly for peptides containing free cysteine residues.
