Can I freeze and thaw reconstituted peptides?
Freezing slows degradation, but each freeze-thaw cycle costs 1-5% of purity, depending on peptide chemistry. Best practice is to aliquot the reconstituted vial into single-use volumes before freezing, so each aliquot is thawed once. Avoid freeze-thawing the same aliquot twice. Detailed aliquot strategy is at reconstitution storage.
