How research peptides are made and tested: from synthesis to COA
How synthetic research peptides are assembled and analysed, and what each section of a certificate of analysis records.
HPLC purity vs net peptide content: two numbers that are often confused
In an illustrative example, a batch shows 98% HPLC purity yet only 80% peptide by weight. This page explains why the two figures differ and how to read each on a COA.
Common impurities in synthetic peptides and how labs detect them
The impurities that arise in synthetic peptides, the analytical methods that reveal them, and the narrow scope of the FDA's 2021 impurity thresholds.
