Streamline your workflow with free custom aliquoting services.
Order lyophilized aliquots and avoid storing aliquots in solution. Your first 10 aliquots are free. Aliquoting is one of the most practical ways to reduce handling-related peptide instability while making routine use easier and more reproducible.
Many peptides are sensitive to repeated freeze-thaw cycles. Small aliquots can be used once and discarded or stored only briefly after reconstitution, which helps protect peptide quality.
Peptides are generally most stable in lyophilized form. Residues such as cysteine, methionine, tryptophan, asparagine, and glutamine are often more prone to degradation in solution.
Instead of repeatedly weighing small amounts from a larger container, aliquots can be prepared during packaging so the peptide is ready for practical day-to-day use.
Aliquoting can reduce the number of handling variables introduced during in-house processing. This can help improve consistency from experiment to experiment.
Reduce assay failure and improve productivity
In-house aliquoting can introduce extra steps and additional experimental variability. A ready-to-use aliquot format can reduce time spent on handling and troubleshooting, especially when the same peptide is used repeatedly over a long project.
Prevent contamination from multiple users
The more users who repeatedly access the same stock solution or parent container, the greater the chance of introducing contamination or inconsistent handling.
Increase convenience
Small aliquot tubes are often easier to handle than a larger storage bottle, especially when only small working amounts are needed.
Exposure to moisture can greatly reduce the long-term stability of lyophilized peptides. Aliquoting can help minimize repeated exposure during routine handling.
Aliquoting is most helpful when the peptide will be used repeatedly, when the sequence is sensitive in solution, or when handling variability can affect downstream assay quality.
