What are research peptides?
A plain-English introduction to research peptides: what they are, how they are made, and how their quality is documented.
Peptides in one sentence
A peptide is a short chain of amino acids joined by peptide bonds. Chains of roughly 2 to 50 amino acids are usually called peptides; longer chains are called proteins.
What makes a peptide a research peptide
Research peptides are synthetic peptides made for laboratory work: in-vitro experiments, assay development and analytical reference. Each one is defined by its amino-acid sequence, molecular formula and molecular weight, which is why reputable suppliers list these details on every product page.
How they are made
Most research peptides are produced by solid-phase peptide synthesis, where amino acids are added one at a time to a growing chain anchored to a resin. The finished peptide is cleaved from the resin, purified (usually by HPLC) and freeze-dried.
Why they arrive as a powder
Freeze-drying (lyophilisation) removes water and leaves a stable white powder in a sealed vial. Lyophilised peptides keep far better than solutions, which is why they are supplied this way. Our storage guide covers temperature, moisture and light.
How quality is documented
A certificate of analysis (COA) records a batch's purity, usually measured by HPLC, and its identity, usually confirmed by mass spectrometry. Our COA guide explains each section, and our batch documentation page shows the certificates for our current stock.
