Custom peptide synthesis
Catalogue and bespoke sequences, from milligram research batches to production scale.
We synthesise catalogue and fully bespoke peptides — linear, cyclic, modified or labelled — using solid-phase chemistry tuned to each sequence. Every project starts with a feasibility review so you know the route, the expected purity and the timeline before synthesis begins.
Purity
≥98% typical
Scale
mg – kg
Format
Lyophilized powder
What is included
Solid-phase synthesis
Fmoc chemistry with resin and coupling strategies selected per sequence, including difficult and aggregation-prone targets.
Modifications
Acetylation, amidation, PEGylation, lipidation, cyclisation, disulfide bridges, biotin and fluorescent labels.
Purification
Preparative RP-HPLC with method development to reach the purity specification agreed for your project.
Scale flexibility
Milligram screening quantities through to multi-gram and kilogram production campaigns.
What you receive
- Feasibility review and synthesis route proposal
- Purified peptide at the agreed purity specification
- Certificate of Analysis with RP-HPLC and LC-MS data
- Lot number registered in the public verification portal
