What is KPV?

KPV is the C-terminal tripeptide fragment of alpha-MSH (Lys-Pro-Val). It is used in intestinal epithelial and macrophage culture to study cytokine expression, barrier integrity and melanocortin signalling, and NuVion stocks it in Australia as a 10mg lyophilised vial.

  • C-terminal tripeptide fragment of alpha-MSH (Lys-Pro-Val)
  • Used in intestinal epithelial and macrophage culture models
  • Applied in cytokine expression and barrier integrity assays
  • Supplied lyophilised, purity by RP-HPLC and identity by mass spectrometry

KPV structure and research use

KPV is residues 11 to 13 of alpha-melanocyte-stimulating hormone, the last three amino acids of the 13 amino acid parent. At three residues it is one of the smallest peptides in the range. In the laboratory it is used in intestinal epithelial and macrophage models for work on cytokine transcription, barrier integrity and melanocortin signalling. It is also the fourth peptide in the KLOW blend.

KPV research applications

  • NF-kB luciferase reporter assays in epithelial cell lines stimulated with TNF-alpha or IL-1beta, with and without KPV
  • Nuclear translocation of p65 followed by immunofluorescence, live imaging of tagged p65 or Western blots of cell fractions
  • IL-8, IL-6 and TNF-alpha secretion by ELISA and MAP kinase phosphorylation blots in Caco-2, HT-29 and Jurkat cells
  • PepT1 transport studies using glycyl-sarcosine competition, pH dependence and siRNA knockdown in transporter-expressing cell lines

Storing and handling KPV

Before reconstitution
Keep the sealed vial cool, dry and out of direct light. General practice for lyophilised peptides.
After reconstitution
Reconstitute with bacteriostatic or sterile water, store at 2 to 8°C and avoid repeated freeze-thaw cycles. No stability-tested shelf life is published for this product.

KPV questions

Where can I buy KPV in Australia?
NuVion stocks KPV in Australia as a 10mg vial of lyophilised powder, posted from Australian stock on a tracked express service. A sample was analysed by Janoshik Analytical on 10 April 2026, with purity of 99.42% by RP-HPLC. It also comes in the Tissue Repair Set (Extended). Bacteriostatic water is sold separately. KPV is supplied as a research material only and is not on the Australian Register of Therapeutic Goods.
What is KPV used for in research?
KPV is used as a tool compound in cell-based studies of NF-κB signalling, particularly the nuclear import of p65, and as a substrate in PepT1 transport assays. It also appears in in vitro antimicrobial work against S. aureus and C. albicans, and as a model tripeptide in hydrogel release and chromatography method development.
How does KPV work at the cell level?
The best-characterised activity of KPV in cell culture is inhibition of NF-kB signalling. It is studied for its effect on nuclear translocation of the p65 subunit and on transcription of cytokine genes such as IL8, IL6 and TNF. The KPV research profile covers the mechanism in full.
How does KPV differ from alpha-MSH?
KPV is only the last three residues of the 13-residue hormone and lacks the His-Phe-Arg-Trp core that binds melanocortin receptors. The research compound also has a free C-terminal carboxylic acid, where alpha-MSH is amidated.
What does the proline residue do in the KPV sequence?
The proline at position 2 restricts backbone conformation and makes the Lys-Pro bond resistant to many aminopeptidases. This slows breakdown in serum-containing medium compared with an unconstrained tripeptide. The lysine at position 1 gives a net positive charge at neutral pH.
How is KPV quantified if it does not absorb at 280 nm?
KPV is quantified by absorbance at 214 nm or by a mass-based preparation. The sequence has no tryptophan or tyrosine, so absorbance at 280 nm cannot be used.
What does KPV stand for?
K, P and V are the one-letter codes for its three amino acids: lysine, proline and valine.
Which blend contains KPV?
KLOW, which combines KPV with GHK-Cu, BPC-157 and TB-500 in a single vial. GLOW is the same blend without KPV.
