Reference reading on how research compounds are described, tested and documented.

• How to read a certificate of analysis

  What a certificate of analysis is, what each part of it reports, and how to match one to the vial it belongs to.

• How peptide purity is measured

  How HPLC and mass spectrometry are used to examine a synthetic peptide, and what a purity percentage does and does not mean.

• What lyophilized means

  Lyophilization is freeze-drying. How the process works, why research peptides are supplied this way, and why the contents of a vial can look so small.
