A practical procurement checklist helps researchers verify that they are ordering the right peptide for their needs, avoiding common pitfalls that can delay experiments or compromise results. Use this checklist before placing any peptide order.
Verify the peptide sequence and any modifications. Confirm that the sequence matches your requirements and that any modifications are correctly specified. Check that the sequence is written in the correct orientation (N-terminus to C-terminus) and that any modifications are clearly indicated.
Verify purity and quantity. Confirm that the purity specification meets your requirements (typically ≥95% or ≥98% for most research applications). Confirm that the quantity is sufficient for your planned experiments, with a buffer for potential losses. Check that the peptide is supplied in the appropriate form (lyophilized powder or solution).
Verify pricing and lead time. Confirm the total cost including shipping and any customs fees. Check the estimated delivery date and confirm that it meets your timeline. For custom peptides, confirm the synthesis and purification specifications.
Verify documentation and shipping. Confirm that a COA with HPLC and MS data will be provided. Check shipping conditions (temperature, packaging) and confirm that they are appropriate for the peptide. Verify customs documentation requirements for international shipments.
