A research peptide is a synthetically manufactured peptide compound sold strictly for laboratory research use. Research peptides are not approved drugs — they have not undergone FDA review for human use, and are sold under Research Use Only (RUO) labeling.
What Peptides Are
Peptides are short chains of amino acids — typically 2 to 50 residues — that act as signaling molecules in biology. Many are derived from larger proteins (e.g., a fragment of a hormone) or are entirely synthetic compounds engineered to bind specific cellular receptors.
What Researchers Use Them For
- Receptor binding studies
- Cell-based assay development
- In vitro biochemistry and signaling pathway research
- Animal-model pharmacology research (in approved settings)
- Reference standards for analytical method development
