Buying KPV — Frequently Asked Questions
How is KPV purity and molecular identity verified per batch?
Each Peptide.Express KPV batch is tested by an independent third-party analytical laboratory using reversed-phase high-performance liquid chromatography (RP-HPLC) against a >=99% purity specification and mass spectrometry to confirm the ~342.4 Da molecular ion. Researchers receive a lot-matched Certificate of Analysis showing the chromatogram, mass spectrum, and lot identifier.
How should lyophilized and reconstituted KPV be stored?
Unopened lyophilized KPV vials should be stored desiccated at -20 °C away from direct light upon arrival. Once reconstituted into sterile aqueous stock, KPV should be divided into single-use polypropylene aliquots and frozen at -20 °C or -80 °C, keeping working aliquots at 2 °C to 8 °C only for short-term bench experiments.
Is KPV approved by the FDA?
No, KPV is not approved by the U.S. Food and Drug Administration for any therapeutic, diagnostic, cosmetic, or dietary indication. KPV remains an unapproved investigational research tripeptide supplied strictly for in-vitro and preclinical laboratory investigation.
