How Research Peptides Are Made: Solid-Phase Peptide Synthesis Explained
June 10, 2026 · by Administrator
Nearly all modern research peptides are produced by solid-phase peptide synthesis (SPPS), a method that revolutionised peptide chemistry.
Building a chain, one residue at a time
In SPPS, the first amino acid is anchored to a solid resin bead. Each subsequent amino acid is added in a controlled, repeating cycle of coupling and deprotection, extending the chain one residue at a time in a defined sequence.
Purification and characterisation
Once the sequence is complete, the peptide is cleaved from the resin and purified — commonly by preparative HPLC — then characterised for identity and purity. You can review these terms in the glossary.
Why it matters for research
Because the sequence is defined and the material is purified and tested, SPPS produces consistent, reproducible research compounds. See how each batch is verified on our quality page.
