Basics

What are peptides?

Short chains of amino acids, large enough for specific interactions and small enough for chemical synthesis. An introduction to structure, nomenclature and research.

Understanding HPLC: how purity is measured

What is behind the percentage on the certificate of analysis, how a chromatogram is generated and why the method matters as much as the result.

Reading the certificate of analysis

A CoA is a batch's identity document. What information it must contain, how to recognise a reliable certificate and how the QR code on the label links to it.

Lyophilisate: storage and stability in the laboratory

Freeze-dried peptides are comparatively stable, but not immune. Moisture, heat, light and oxygen are the four factors that matter.
