Research peptide glossary: CoA, HPLC, MS identity, storage, and RUO terms

This glossary defines the terminology procurement, QA, and laboratory teams encounter when evaluating research peptides, lot documentation, storage records, and RUO product pages.

Core documentation terms

Use this glossary as an entity hub for research peptide pages. Each definition is intentionally short, laboratory-framed, and suitable for internal linking from product pages and research guides.

Definitions do not replace institutional SOPs, CoA review, or qualified compliance guidance.

Certificate of analysis (CoA)

A lot-specific document that reports analytical results such as identity, purity, net peptide content, moisture, and other release checks.

HPLC purity

A chromatographic area-percent measure used to estimate the main peptide peak relative to detected impurities under a defined method.

MS identity

Mass spectrometry confirmation that observed mass aligns with expected peptide identity, termini, and modification state.

Net peptide content

The peptide mass fraction after accounting for water, salts, and counter-ions; important for concentration calculations.

lyophilized-peptide">Lyophilized peptide

A freeze-dried peptide format commonly used for shipping and storage before controlled reconstitution in a laboratory workflow.

Reconstitution

The documented addition of a compatible liquid or buffer to lyophilized material to prepare a research stock solution.

aliquot">Aliquot

A smaller labeled portion of reconstituted stock prepared to limit freeze-thaw history and preserve traceability.

Freeze-thaw history

The number and conditions of thawing and refreezing events recorded for a research stock or aliquot.

Research use only (RUO)

A material-use classification for laboratory research workflows, not clinical, diagnostic, therapeutic, veterinary, food, drug, or cosmetic use.

GHRH analogue

A research reference related to growth hormone releasing hormone pathway studies.

Secretagogue

A research term for references studied in receptor systems associated with secretion signaling.

GLP-1 analogue

A research category for incretin-related analogue materials studied in receptor and metabolic pathway models.

Cathelicidin

A peptide family term often associated with LL-37 and innate-immunity model literature.

Incretin

A signaling category used in metabolic research literature for GLP-1 and related analogue comparisons.

Lot traceability

The ability to link a vial, CoA, purchase order, storage record, and experiment record back to a specific production lot.

How to use the glossary

When a product page references CoA, HPLC purity, MS identity, net peptide content, reconstitution, or RUO status, link back to this glossary so search engines and readers can connect the entity graph.

Glossary pages improve semantic search because they define the vocabulary behind the catalog rather than only listing products.
