What are research peptides?
Peptides are short chains of amino acids used as precise signalling tools in laboratory research, including assay development, receptor binding studies, and antibody production.
Are your products intended for human or veterinary use?
No. Every product we supply is strictly for in-vitro laboratory research. They are not for human or veterinary consumption, administration, or diagnostic use.
What purity are your peptides?
Our compounds are typically supplied at 98% or higher, verified by HPLC. The exact purity figure for your batch is stated on the Certificate of Analysis included with the shipment.
Do you provide a Certificate of Analysis?
Yes. Every batch is characterised by HPLC and mass spectrometry, and a Certificate of Analysis is supplied with each order so you can verify the material in your records.
How should peptides be stored?
Lyophilised powders should be stored dry at -20°C and are stable for long periods. Once reconstituted, follow the storage guidance on the vial label and your own protocol.
How quickly are orders dispatched?
Orders placed on a working day are generally dispatched the same or next working day using tracked delivery within the United Kingdom.
Can I request a custom synthesis?
Yes. Send us your sequence, required purity, and scale, and our technical team will confirm feasibility, lead time, and documentation before anything is produced.
