Aliquoting means splitting a reconstituted peptide into several small, single-use portions. It’s one of the simplest ways to protect material and keep research consistent. Here’s why and how — for laboratory work.
- What it is: dividing one solution into smaller portions (aliquots).
- Why: you thaw only what you need, avoiding repeated freeze–thaw.
- Bonus: reduces contamination from opening one vial repeatedly.
Why aliquot?
Each time a solution is frozen and thawed, the peptide takes a little damage. By splitting it into single-use aliquots, you only ever thaw one small portion at a time — the rest stays frozen and untouched. See why freeze-thaw cycles damage peptides.
A simple approach
- Reconstitute the peptide to your working concentration — see calculating concentration.
- Divide it into small portions sized for a single use.
- Label each with concentration and date.
- Store them cold; thaw one at a time as needed.
