Research Overview
KPV is studied in inflammation-signalling research, including cell-culture models of epithelial and keratinocyte stress and animal models of intestinal barrier function.
Recent work has also used KPV to explore peptide delivery systems such as hydrogels and transdermal methods.

KPV: Research Background
α-Melanocyte-stimulating hormone (α-MSH) is a 13-residue peptide. KPV corresponds to its last three residues (positions 11–13) and is studied as a standalone tripeptide.
Published work describes KPV reducing NF-κB and MAPK inflammatory signalling in epithelial and immune cell models. Studies in intestinal epithelial cells reported uptake through the PepT1 di/tripeptide transporter, and several reports suggest some of its activity does not depend on melanocortin receptor 1, unlike the parent hormone.
More recent research uses KPV as a model payload for delivery systems such as hydrogels, nanoparticles and transdermal formulations.
What the KPV COA Confirms
OxygenLab products are tested by independent third-party laboratories. HPLC reports purity as the main peak’s share of total peak area, and mass spectrometry confirms identity against the expected molecular weight of 342.4 g/mol. Published certificates are on our COA page, and others are available on request; match the lot number on your vial to the report before use in an experiment.

More Questions About KPV
Which part of α-MSH is KPV?
Residues 11–13: Lys-Pro-Val, the C-terminal end of the 13-residue hormone.
How does KPV enter cells in research models?
Studies in intestinal epithelial cells reported transport by PepT1, the di- and tripeptide transporter.
Storage and Handling
- Store lyophilized powder at -20°C for long-term storage, protected from light and moisture.
- Short-term storage at 2–8°C is acceptable for unopened vials.
- Allow the vial to reach room temperature before opening to limit moisture uptake.
- Record batch and lot numbers for every preparation.
