A chemical compound resulting from the breakdown of a peptide through oxidation, deamidation, hydrolysis, or other processes. COAs report the percentage of degradation products to indicate product integrity.
"Degradation Product" is filed under Quality in the PeptideAtlas glossary, alongside 12 other terms in that group.
1 other glossary entry refer to this term in their own definition, which is usually the fastest way to see how it is used in practice.
The percentage of the desired compound in a sample, as opposed to impurities, degradation products, or other contaminants. Research-grade peptides typically claim >98% purity.
A document from a laboratory (ideally third-party) that certifies the identity, purity, potency, and quality of a substance. Essential for verifying research peptide quality.
An analytical technique used to separate, identify, and quantify components in a mixture. Used in COAs to determine peptide purity percentage.
An analytical technique that measures the mass-to-charge ratio of molecules. Used in COAs to confirm peptide identity and molecular weight.
