How to Aliquot Peptides
Aliquoting peptides into smaller quantities helps reduce repeated freeze-thaw cycles, repeated vial opening, contamination risk, oxidation, and aggregation. It is often a practical way to protect peptide stability during routine lab use.
Why aliquoting helps:
- Less repeated freeze-thaw stress
- Less exposure to air and moisture
- Lower contamination risk
- Better preservation of unstable peptides
When Aliquoting Is Most Useful
- Peptides used repeatedly over time
- Oxidation-sensitive or aggregation-prone sequences
- Projects requiring consistent concentration across experiments
- Long-term storage after reconstitution
When aliquoting becomes especially important
If your peptide is sensitive to oxidation, repeated thawing, or handling-related instability, aliquoting can save time and reduce avoidable losses.
- Repeated use planned: aliquot early
- Unstable sequence: reduce handling cycles
- Small working amounts: aliquots simplify routine use
