Research Peptide Supplier Evaluation Checklist (Printable)

Published · Last updated · Publisher: ENOS Labs USA

How to use this checklist

Use this one page checklist when reviewing any research peptide supplier, including us. Each line is something you can verify from documents for the specific lot you receive: a matching lot number, a named laboratory and date, a mass spectrometry identity result, an HPLC chromatogram with method conditions, and clear storage and research use terms.

Lot documentation

  • Certificate is specific to the lot number printed on the vial
  • Testing laboratory is named
  • Analysis date is shown
  • Original laboratory issued document is available on request

Identity

  • Mass spectrometry result is reported
  • Observed mass is shown next to the expected mass
  • Modifications (amidation, acetylation, salts) are stated

Purity and content

  • HPLC chromatogram is shown, not only a number
  • Method conditions are printed (column, gradient, wavelength)
  • Water content or net peptide content is reported where available

Handling

  • Storage temperature is on the label
  • Packaging protects from moisture and light
  • Shipping method suits the compound

Terms

  • Clear research use only terms
  • No health or treatment claims about research compounds
  • Contact details for documentation requests

To continue, see how to evaluate a research peptide supplier, how to read a certificate of analysis, lot traceability, the peptide testing glossary and the compound directory.
