Synthetic peptide fragments
KPV research peptide
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone (residues 11 to 13). Its small size and defined sequence make it a common subject in structure-activity research on melanocortin-derived fragments.
For in-vitro laboratory research only. Not for human or veterinary use.

|---|---|---|
| Purity | HPLC-UV | ≥ 99.0% |
| Net peptide content | Quantitative HPLC | ≥ 100% of label |
| Identity | LC-MS | Matches theoretical mass |
| Appearance | Visual | White lyophilized cake |
| Fentanyl screen | LC-MS/MS | Not detected |
| Heavy metals | ICP-MS | Within specification |

| Endotoxin | LAL | Within specification |
Frequently asked questions
What is KPV?
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone (residues 11 to 13). Its small size and defined sequence make it a common subject in structure-activity research on melanocortin-derived fragments.
How is each KPV lot tested?
Every lot is tested at an ISO/IEC 17025 accredited third-party laboratory against an eight-assay panel: HPLC-UV purity, quantitative net peptide content, LC-MS identity, appearance, a fentanyl screen, heavy metals by ICP-MS, sterility by PCR, and endotoxin by LAL. The certificate is published before the lot ships.
How do I verify the certificate for my KPV vial?
Scan the QR code on the vial label to open the certificate for that exact lot, or search the lot number in the North Wall COA library.
Is KPV for human use?
No. North Wall sells this compound solely for in-vitro laboratory research by qualified researchers aged 21 and over. It is not for human or veterinary use, and North Wall does not provide use, preparation, or dosing guidance.
