Twenty years of peptide science, in every vial.
Peptaura is built on more than two decades of hands-on experience in peptide research and production. Our lab scientists synthesise, purify and independently test every compound we ship — from our ready-made catalogue to fully bespoke, made-to-order sequences.
Science first. Always.
Peptaura was founded by a team of biochemists and clinical researchers who had spent their careers watching the same problem: high-quality research peptides were hard to source consistently in the UK, and even harder to verify. We built Peptaura to be the supplier we always wanted to buy from.
Two decades on, our scientists still oversee every stage — from solid-phase synthesis and preparative HPLC purification through to lyophilisation, sterile filling and cold-chain dispatch. Nothing leaves the facility without an independent Certificate of Analysis on file.
Precision at 15,000 rpm.
Every peptide we produce passes through the centrifuge — the peptide spinner separates the synthesised compound from residual reagents, isolating the pure sequence before it moves on to HPLC purification. It's one of the quiet, unglamorous steps that decides whether a batch is worth shipping.
Ready-made and made-to-order.
Whether you need something off the shelf tomorrow or a bespoke sequence produced to your exact specification, our lab is set up for both.
Ready-made peptide catalogue
A curated library of the most requested research peptides — synthesised in batch, quality-controlled and held in cold storage for immediate UK dispatch.
Made-to-order synthesis
Bespoke sequences produced to your specification. Share the sequence, purity target and quantity — our chemists scope, quote and manufacture in-house.
Independent HPLC & MS testing
Every batch is analysed by third-party laboratories using HPLC and mass spectrometry. Certificates of Analysis are issued per lot and available on request.
cGMP-aligned handling
Cleanroom filling, controlled cold-chain shipping and tamper-evident packaging — the standards we'd want if we were the researcher receiving the vial.
From sequence to sterile vial.
Four stages, every batch, no shortcuts.
- 01
Sequence & scope
Ready-made from catalogue, or a custom sequence submitted through our secure form. Our chemists confirm feasibility, scale and timeline.
- 02
Solid-phase synthesis
Peptides are assembled amino acid by amino acid on resin using Fmoc chemistry, cleaved and purified through preparative HPLC.
- 03
Analysis & release
Independent HPLC purity, mass-spec identity and endotoxin testing. A lot is only released once every result passes specification.
- 04
Cold-chain dispatch
Lyophilised, filled into sterile vials, insulated and tracked from our UK facility to your bench.
Need something we don't stock?
Send us the sequence, target purity and quantity. Our chemists will confirm feasibility, quote a lead time and manufacture it in-house — with the same HPLC verification and Certificate of Analysis as our catalogue products.
- • Custom sequences from milligram to multi-gram scale
- • Modifications: acetylation, amidation, PEGylation, biotinylation
- • Typical lead time 2–4 weeks from confirmation
- • Full COA and mass-spec report included
