Research use only (RUO): reading peptide labels

Understand research use only on a peptide label and compare the stated material, specification and lot certificate without filling gaps from the abbreviation.

Substantially revised to focus on peptide identity and documentation, with clearer explanations and source citations.

RUO means research use only. Novum Peptides states “For laboratory research use only”; use that wording alongside the material description and its certificate.

Read the full statement

Novum’s published scope is laboratory research use only. Keep that statement with the product record rather than reducing the record to the letters RUO. The policy and the certificate serve different purposes.Research-use policy (opens in a new tab)

When comparing research peptide listings, use the full material name and declared form, the vial size and the certificate for the relevant lot. A report should identify the sample and the tests performed; RUO is not a substitute for those fields.WHO certificate model (opens in a new tab)

A specification is a set of requirements; a certificate contains reported observations against stated requirements. Keep a supplier’s nominal description separate from a measured result. For example, a 10 mg label and an assay in milligrams per vial belong in different fields.Bachem analytical guide (opens in a new tab)Semax report (PDF) (opens in a new tab)

Make a focused enquiry

If a field is missing, ask for the document that addresses it: the sequence or structural specification for identity, the selected lot report for results, or the supplier’s written scope statement. Retain the question as unresolved until the relevant information is supplied.WHO certificate model (opens in a new tab)
