Research Peptide Glossary
A concise glossary for reading Panda’s research pages, product specifications, COAs, and quality documentation.
COA
Certificate of Analysis. A laboratory report documenting analytical findings for a submitted sample, often including identity, purity, method details, batch reference, and verification information.
HPLC
High-performance liquid chromatography. An analytical method used to separate sample components and estimate purity by peak area under a defined method.
LC-MS / MS
Liquid chromatography–mass spectrometry / mass spectrometry. Analytical methods used to support molecular identity confirmation through mass-related data.
Batch / lot
A traceability identifier connecting a product record, physical label, and COA. Batch-level documentation is more useful than generic product-level claims.
CAS number, molecular weight, and sequence
Reference identifiers used to define compound identity. CAS numbers identify substances in chemical registries; molecular weight and sequence help describe peptide composition.
Lyophilized powder
A freeze-dried presentation commonly used for research compounds. This glossary term is descriptive only and does not imply instructions for preparation, application, or non-research use.
