PEPTIDE LABORATORY

Peptide testing,
with the context that matters.

Bring a clear analytical question to your peptide laboratory. Define the sample, the requested tests and the documentation you need before analysis begins.

DEFINE YOUR SCOPE

One sample. Clearly defined questions.

Peptide testing should begin with the purpose of the work. Ask the laboratory which methods and reporting options are appropriate for your sample.

Identity

Specify the claimed compound and ask what evidence the agreed method can provide.

Explore Identity

Purity

Ask how purity will be assessed and how the reported value should be interpreted.

Explore Purity

Amount or concentration

Request this explicitly when needed. Do not assume a purity result includes an amount or concentration measurement.

DOCUMENTATION

A COA connected to your sample.

Your reporting request should identify the sample description, client-supplied lot reference, required tests and any supporting analytical output you need.

  • Confirm the sample description and lot reference
  • Agree on methods, result units and report scope
  • Ask about chromatograms or spectra where applicable

Understand COA reporting

BEFORE SUBMISSION

Let the laboratory confirm the details.

Share the material’s stated identity, physical form, approximate amount and your testing objective. The laboratory will need to confirm acceptance, sample requirements and the quote. Do not send materials without instructions.

HELP & GUIDANCE

Peptide testing questions

How do I choose a peptide laboratory?

Start with the analytical question you need answered. Ask the laboratory to confirm the sample types it accepts, the methods available, what the report will include, its limitations and the current quote before sending material.

Are purity, identity and sample quantity the same result?

Treat these as separate analytical questions. Ask which results are actually included in your testing scope and read the method and units beside each value. Do not infer an unreported test from another result.

How much sample should I send?

Ask the laboratory to confirm the quantity, container, preparation and shipping instructions for your specific material and requested tests. Do not send samples before receiving acceptance instructions.

Discuss your peptide testing requirements.

Start with the compound, sample form and question you need answered.
