[QUOTE="Cataceous, post: 266286, member: 38109"] In my experience there's minimal loss of potency in one freeze-thaw cycle with the peptides I use. Peptide Sciences has [URL='https://www.peptidesciences.com/information/peptide-storage/']a page[/URL] on the subject. Most relevant: [INDENT][I]Reconstituted (Mixed)[/I][/INDENT] [INDENT][/INDENT] [INDENT][I]Short term - Peptide solutions generally remain stable up to 30 days when stored in the refrigerator at 4C (39F) depending on the length of the peptide sequence and its inherent[/I][/INDENT] [INDENT][I]instability factors.[/I][/INDENT] [INDENT][/INDENT] [INDENT][I]Long term - If peptides absolutely must be stored in solution, sterile buffers at pH 5-6 should be used if possible, and the peptide solution should be separated into aliquots to avoid repeated freezing and thawing.
