Eternal Peptides provides a lot-specific Certificate of Analysis for every KPV lot. Each COA documents identity by HPLC and mass spectrometry (confirming MW 342.43 g/mol and the Lys-Pro-Val sequence), purity, sterility (USP <71>), and endotoxin levels (LAL, typically <1.0 EU/mg), plus lot-specific storage guidance. Testing is conducted by independent third-party laboratories including Janoshik. COAs are batch-numbered on the vial and available on the Lab Tests page.
Store unopened lyophilized vials at -20°C in a dry environment protected from light and moisture, with containers kept tightly sealed until required. When preparing a working solution, use an appropriate sterile reconstitution solution or compatible laboratory buffer in accordance with your laboratory’s validated procedures. Storage conditions for prepared solutions should be determined by the requirements of the research protocol, with aliquoting commonly employed to help preserve sample quality during repeated use. Always follow applicable institutional biosafety, laboratory handling, and disposal requirements.
KPV is strictly for laboratory research purposes only and is not approved by the FDA or any regulatory authority for human consumption, veterinary use, clinical administration, therapeutic applications, or diagnostic procedures. Its safety and efficacy in humans have not been established. Purchasers are solely responsible for compliance with all applicable regulations and institutional policies.
