A complete reference on research-use-only peptides — how they are classified, how they are supplied, and what documentation legitimate research supply carries.
Research-use-only peptides sit inside a defined supply framework. This reference summarises that framework end to end: how RUO material is classified, how it is manufactured and tested, and what documentation should always accompany a legitimate research shipment.
Supply-chain framework
- Solid-phase synthesis (SPPS) by a documented peptide manufacturer.
- Analytical QC — HPLC purity, LC-MS identity, counterion, endotoxin where relevant.
- Lyophilisation into research vials with lot-specific batch identifiers.
- Third-party analytical verification for batches supplied to research customers.
- Documentation transfer — COA and batch record supplied with the material.
Documentation expected on every RUO shipment
- Batch identifier and synthesis date traceable to the lot record
- HPLC purity ≥98% (typically ≥99% for peptides under 30 residues)
- LC-MS confirmed monoisotopic or average mass within ±0.5 Da of theoretical
- Counterion identity and content (acetate or trifluoroacetate) reported
- Bacterial endotoxin and residual solvents per the analytical method
