Peptide solutions are generally stable for up to 30 days when refrigerated at 4C (39F) Stability depends on peptide length, amino acid composition, and inherent instability factors Long-Term Storage If peptides must be stored in solution for extended periods: Use sterile buffers with a pH between 5 and 6 when possible Divide solutions into small aliquots to prevent repeated freeze-thaw cycles Store frozen at 80C (112F) for maximum stability Repeated thawing and refreezing should be avoided, as it accelerates peptide breakdown
