About Protiva
Protiva supplies synthetic research peptides to laboratories and qualified researchers in Great Britain, with an emphasis on documented quality and straightforward, transparent service.
What we do
We source and supply lyophilised peptides specified to ≥99% purity by HPLC. Every product in our catalogue is intended solely for in-vitro laboratory research and development. We do not make, and do not permit, any human, veterinary, clinical or diagnostic use of our materials.
Our approach to quality
Purity is only meaningful when it can be verified. Each batch is tested by independent third-party laboratories using high-performance liquid chromatography for purity and mass spectrometry for identity confirmation; copper-containing and other relevant products are additionally assessed by methods such as ICP-MS, and endotoxin screening by LAL where appropriate. Certificates of analysis accompany each batch.
Dispatch & support
Orders are processed within 1–2 business days and shipped tracked from within Great Britain. Our team is available by email for questions about specifications, documentation and orders.
