What is KPV?

KPV is a tripeptide made of lysine, proline and valine (Lys-Pro-Val). It corresponds to residues 11–13, the C-terminal end, of alpha-melanocyte-stimulating hormone (α-MSH), a 13-amino-acid peptide of the melanocortin family. At only three residues it is one of the smallest compounds in the V8 Peptides catalog.

Researchers use KPV to ask which activities of α-MSH can be traced to its C-terminal fragment alone. Published work includes NF-κB signaling studies in cultured cells and experiments in intestinal epithelial models, where uptake of the tripeptide by the PepT1 transporter has been investigated. It is supplied as lyophilized powder in a 5 mg vial.

Where it is used in the lab

  • Melanocortin-pathway studies using a minimal α-MSH fragment
  • NF-κB signaling readouts in cell-culture models
  • Peptide-transport experiments in intestinal epithelial cells

Reconstitution & storage for research

Adding 1 mL of diluent to the 5 mg vial gives 5 mg/mL; adding 2 mL gives 2.5 mg/mL. Short peptides like KPV dissolve quickly. At 2.5 mg/mL, a 100 µL aliquot contains 250 µg, and a 20 µL aliquot contains 50 µg. For other volumes, the reconstitution calculator returns mg/mL and per-aliquot content instantly.

A sterile diluent such as bacteriostatic water is the usual choice for multi-use research vials. Let the diluent trickle down the vial wall, give the powder time to wet, and roll the vial between your fingers until no particles remain. Avoid shaking or vortexing at high speed.

Storage conditions

  • Dry material: refrigerated (2–8 °C) on arrival; frozen (−20 °C) when it will not be used soon.
  • Handling: limit exposure to warmth, moisture and light, and wipe the stopper with an alcohol swab before each puncture.
  • Reconstituted material: store at 2–8 °C, note the date and mg/mL value in your lab record, and freeze single-use aliquots rather than refreezing one vial.

Quality & testing

Purity for KPV is measured by HPLC on a per-batch basis, with a ≥98% release threshold. The matching Certificate of Analysis is posted at /coa, which lets a lab verify what it received instead of relying on a generic specification sheet.

  • Chromatographic purity (HPLC %)
  • Identity check for the stated compound
  • Lot number and test date for traceability
  • Form supplied and recommended storage

Each sealed vial carries research-use labeling and ships domestically in the US. Orders are paid by invoice or Zelle.
