A complete Kiwi Peps 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 in New Zealand.
RUO peptide supply-chain framework
- Solid-phase peptide synthesis (SPPS) by a documented manufacturer.
- Analytical QC — HPLC purity, LC-MS identity, counterion identity, water content, 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
| Document | Purpose |
|---|---|
| Batch COA | Verifies identity, purity and counterion for the specific lot |
| HPLC chromatogram | Visual verification of purity value |
| LC-MS trace | Confirms observed mass matches theoretical |
| RUO label | Explicit classification on outer box and inner vial |
- 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
Research-use-only peptides FAQ
What are research-use-only peptides?
RUO peptides are reference-material peptides manufactured and tested as research reagents, not as therapeutics. They are supplied strictly for laboratory research use.
What documentation should accompany an RUO peptide shipment?
A batch-level COA with HPLC purity, LC-MS identity, counterion identity and RUO labelling on both outer box and inner vial.
Where can New Zealand researchers source RUO peptides?
Kiwi Peps supplies research-use-only peptides at ≥98% HPLC purity with third-party COA and same-day domestic dispatch.
