Peptides Defined
A peptide is a sequence of amino acids linked by peptide bonds. Peptides are typically shorter than proteins, ranging from a few residues to around fifty. In a research context, peptides are synthesized to a known sequence so that laboratories can use them as predictable reference materials.
How Research Peptides Are Made
The dominant production method is solid-phase peptide synthesis (SPPS). Amino acids are added one at a time onto a resin, then the finished chain is cleaved from the resin and purified.
After synthesis, peptides are characterized analytically — typically by HPLC for purity and mass spectrometry for identity — before being lyophilized into a stable powder for shipment.
Why Researchers Use Them
Research peptides function as identity and concentration references. They allow analytical chemists to calibrate instruments, biochemists to develop in-vitro assays, and academic groups to study peptide-protein interactions under controlled conditions.
What Research Peptides Are Not
Research peptides are not approved drugs. They are not for human consumption, are not therapeutic products, and are not intended to diagnose, treat, cure, or prevent any disease. Reputable suppliers restrict sales to qualified laboratories and require buyers to confirm in-vitro research use.
