Lyophilization and peptide stability
Every Merit research peptide ships as a lyophilized (freeze-dried) powder rather than a ready-to-use liquid. There's a reason — and it's ...
The Certificate of Analysis explained
A Certificate of Analysis (COA) is the document a third-party laboratory issues to certify that a specific production lot of a peptide pa...
Mass spectrometry for peptide identity verification
HPLC tells you how much target peptide is in your sample. Mass spectrometry tells you whether the molecule present is actually the molecu...
