Aliquoting
Aliquoting is the practice of dividing a reconstituted peptide solution into multiple smaller volumes, each stored in a separate container. This allows individual aliquots to be thawed for use while the remaining material stays frozen.
The primary purpose of aliquoting is to minimize freeze-thaw cycles on the bulk solution. Each freeze-thaw cycle exposes the peptide to ice crystal formation, concentration effects at the ice-liquid interface, and potential aggregation — all of which can degrade the material.
Best practice: reconstitute the full vial, divide into single-use aliquots in sterile microcentrifuge tubes, flash-freeze in liquid nitrogen or a -80°C freezer, and store at -20°C or below.
