Basics
Definition, regulatory context, and areas of application for synthetic research peptides — what they are, what they are used for, and what “Research Use Only” means.
Peptides are short chains of amino acids — the building blocks of proteins. They are formed by linking two or more amino acids via peptide bonds. Depending on the number of amino acids, they are referred to as dipeptides (2 AA), tripeptides (3 AA), oligopeptides (up to approx. 20 AA), or polypeptides (more than 20 AA).
Peptides occur naturally in the human organism and fulfill diverse functions — as hormones, neurotransmitters, signaling molecules, and enzyme regulators. Synthetic peptides are chemically produced analogs of these naturally occurring compounds or entirely newly designed molecules.
The term “Research Peptide” — in German: Forschungspeptid — refers to synthetically produced peptides intended exclusively for use in preclinical research. They are not intended for human or animal consumption and do not have regulatory approval as medicinal products.
Research peptides are typically used in the following research contexts:
Research Use Only
The designation “Research Use Only” (RUO) identifies products intended exclusively for research purposes in authorized laboratory environments. They are not intended for diagnostic, therapeutic, or other clinical applications.
In the European Union, research peptides are not subject to authorization as medicinal products as long as they are marketed and used exclusively for research purposes. They do not fall under the Medicinal Products Directive 2001/83/EC if they are not intended for use in humans or animals.
Suppliers of research peptides are required to clearly label the intended use and ensure that products are supplied exclusively to authorized research institutions. For their part, buyers are responsible for complying with applicable national regulations.
Since research peptides are used in preclinical research models, their analytical quality is critical for the reproducibility of research results. The recognized standard for research-grade peptides includes:
