Research & Education

The science of peptides, explained clearly.

Peptides sit at the centre of modern life-science research. This is our plain-language primer — what they are, how they're studied, and how to read the data responsibly.

What is a peptide?

A peptide is a short chain of amino acids — the same building blocks that make up proteins, just fewer of them. Where a protein may contain hundreds of amino acids, a peptide typically has between two and fifty.

Because they're small and specific, peptides are widely used as research tools to probe how biological signalling pathways work. Their sequence determines their shape, and their shape determines how they interact with receptors and other molecules.

How peptides are studied

Research peptides are typically supplied as a lyophilised (freeze-dried) powder and handled under controlled conditions.

Reconstitution

The powder is dissolved in an appropriate solvent under sterile, controlled conditions.

Assay design

Researchers define the in-vitro model and the measurable endpoints of interest.

Measurement

Effects are observed and quantified against controls to ensure validity.

Documentation

Methods and results are recorded so findings can be reproduced and reviewed.

Example characterisation data fields on a certificate of analysis
FieldWhat it tells you
Purity (HPLC)Proportion of the sample that is the target compound.
Mass (MS)Confirms the molecular weight matches the expected sequence.
SequenceThe exact order of amino acids in the chain.
Net peptideActual peptide content, accounting for salts and water.
StorageConditions to preserve stability over time.

How to read characterisation data

A certificate of analysis (COA) is the single most useful document for a research peptide. It tells you what the compound is, how pure it is, and how to store it.

Purity above 98% is a common benchmark for research-grade material, but the right specification depends on your assay. When in doubt, request the COA and review the method before you begin.
