Research peptides, verified lot by lot.
Every lot is tested by HPLC and mass spectrometry before it ships, and its certificate is published under the lot number on the vial. Check the data first, then order.
- HPLC and MS on every production lot
- Public COAs searchable by lot number
- Lyophilized in sealed, crimped glass vials
- Tracked shipping to most countries
Most requested
Priced per box of ten vials.
How a lot is released
No lot is listed for sale until it has passed each of these steps.
Synthesis
Solid-phase peptide synthesis from protected amino acids, with sequence and lot recorded at the start.
Purification
Preparative reverse-phase HPLC separates the target peptide from truncated and deletion sequences.
Lyophilization
Freeze-dried into a stable powder cake, filled and crimp-sealed in glass vials.
Testing
Analytical HPLC confirms purity; mass spectrometry confirms the molecular weight matches the sequence.
Publication
The certificate is published under the lot number before the first box of that lot ships.
