Peptide Research Glossary: Core Laboratory Terms

Peptide research uses technical language that can be easy to overread. This glossary defines common terms in a research-literacy context, without dosing, administration, or human-use guidance.

Peptide

A peptide is a chain of amino acids connected by peptide bonds. In research catalogs, peptide names may refer to a sequence, abbreviation, or supplier naming convention.

Sequence

A sequence describes the order of amino acids in a peptide. Sequence information helps researchers compare literature references and product naming.

Assay

An assay is a test or measurement approach used in a research setting. The assay determines what type of observation can be made and what limitations apply.

Control

A control is a comparison condition used to interpret a result. Without appropriate controls, it is harder to understand whether an observed difference is meaningful.

Endpoint

An endpoint is the measurement or observation a study is designed to evaluate. Endpoints should be interpreted within the model and method used.

Replicate and reproducibility

Replicates repeat a measurement or condition. Reproducibility describes whether a finding can be observed again under appropriate conditions.
