Description
Tripeptide studied in anti-inflammatory research. Supplied strictly for laboratory and in-vitro research use — not for human or veterinary consumption.
KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone. At three residues it is one of the smallest peptides in the catalogue, and is correspondingly stable and easy to dissolve. It should not be confused with KdPT, a related analogue built on D-proline.

Every lot ships against its own certificate of analysis. Search by lot number on the certificates of analysis page, or check the paperwork before you order.
KPV is supplied for laboratory research use only. It is not a drug, food or cosmetic, and it is not for human or veterinary use.
| Reconstitution | Readily soluble in water; bacteriostatic water or sterile water. |
|---|---|
| Storage, lyophilised | -20 °C, sealed and desiccated, protected from light. |
| Storage, reconstituted | 2-8 °C, protected from light. Use within 2-4 weeks, or freeze single-use aliquots at -20 °C for longer holds. |
| Shipping | Shipped at ambient temperature. Lyophilised material tolerates transit without a cold chain; move it to the freezer on arrival. |
Working notes
- Let a vial come to room temperature before opening it. Opening a cold vial draws in moist air, and lyophilised powder takes up water quickly.
- Add the diluent slowly down the inside wall of the vial rather than directly onto the powder cake, and let it dissolve on its own. Shaking a peptide solution is the fastest way to denature it.
- Wipe the stopper with alcohol before every draw, and keep solutions out of direct light.
- Repeated freeze-thaw cycles cost you more purity than time in the fridge does. If a vial will be used over weeks, aliquot it once and freeze the aliquots.
