KPV peptide is a synthetic tripeptide compound produced for research applications. A tripeptide is a peptide chain consisting of three amino acids linked together. This specific sequence contains lysine, proline, and valine amino acids. Peptide fragments are shorter segments of amino acid chains studied for their structural properties. These fragments are investigated in laboratory research because they help scientists understand how specific amino acid sequences contribute to molecular properties. This synthetic peptide origin ensures batch-to-batch consistency for research protocols. The compound represents a defined three-amino-acid sequence designed for experimental study. Researchers examine this tripeptide’s properties within controlled laboratory conditions without therapeutic context.

What is KPV and where does its sequence originate?
KPV is a tripeptide (Lys-Pro-Val) derived from the C-terminal sequence of alpha-melanocyte stimulating hormone (α-MSH). It corresponds to the 11-13 residues of α-MSH and is studied in research models as a functional fragment that retains some of the signalling properties of the parent melanocortin peptide, particularly those related to anti-inflammatory pathway modulation.
What receptors has KPV been investigated for in research?
KPV has been studied in research models for potential interactions with melanocortin receptors — particularly MC1R and MC3R — and with intracellular inflammatory pathway components. Its small size relative to full-length α-MSH means it likely has different binding dynamics at these receptors. Research has also examined potential interactions with gut epithelial cells and immune cell populations, where inflammatory signalling pathway modulation has been reported in preclinical studies.
What in vitro models are used to study KPV?
Standard in vitro research models for KPV include macrophage and dendritic cell lines stimulated with pro-inflammatory mediators (LPS, TNF-α), intestinal epithelial cell lines used to study barrier function and inflammatory signalling, and reporter gene assays for NF-κB pathway activation. These models allow the compound’s effects on defined inflammatory signalling endpoints to be characterised under controlled conditions.
How should KPV be stored and reconstituted?
KPV is supplied as a lyophilised powder and should be stored at -20°C. Due to its small molecular weight (approximately 340 Da), it is generally highly water-soluble. Reconstitution in sterile water or PBS is standard. Solutions should be aliquoted to avoid repeated freeze-thaw and stored at -80°C for extended use.
Is KPV for human use?
KPV as supplied by Elivena is for research use in controlled laboratory settings only. It is not approved for human therapeutic, dietary supplement, or clinical administration outside of formally regulated research contexts.
What is the difference between KPV and KPV?
KPV and KPV are the same compound — the tripeptide Lys-Pro-Val derived from the C-terminal sequence of α-MSH — supplied at different quantities to accommodate varying research programme scales. The format is suited to research programmes requiring higher compound volumes, extended dose-response studies, or parallel experimental series across multiple model systems.
What is the molecular weight and physicochemical profile of KPV?
KPV has a molecular weight of approximately 340 Da and is a highly hydrophilic tripeptide at physiological pH. Its net charge is positive due to the lysine side chain. High aqueous solubility makes it straightforward to prepare stock solutions in sterile water or PBS without organic co-solvents. These properties support its application in cell-based research systems where organic solvents would be cytotoxic.
What inflammatory pathway research has been conducted with KPV?
Preclinical research with KPV has examined its effects on NF-κB pathway activation in macrophage and intestinal epithelial models, cytokine secretion profiles in LPS-stimulated immune cell cultures, and barrier integrity markers in intestinal epithelial cell monolayers. These studies are conducted as controlled in vitro experiments and are used to characterise the compound’s effects on defined inflammatory signalling endpoints.
What controls are recommended for KPV research experiments?
Recommended controls include vehicle-only controls (buffer at matched pH and ionic strength), a scrambled tripeptide control (e.g. VKP or PVK) to confirm sequence specificity, and positive controls using established anti-inflammatory pathway modulators (e.g. dexamethasone for NF-κB inhibition) to validate assay sensitivity. These controls are standard practice for rigorous tripeptide research studies.
Is KPV intended for therapeutic use?
No. KPV as supplied by Elivena is for research use in controlled laboratory settings only. It is not approved for human administration, therapeutic application, or dietary supplement use outside of formally regulated research contexts.

Identity and purity by LC-MS
Researchers often ask
Is KPV for human use?
No. KPV is sold for laboratory research only. It is not for human or veterinary use, and it is not a drug, food or cosmetic.
How do I find the lab report?
Use View COAs on the product page, or search the COA library by compound name. The summary is public; the signed PDF reports are available to signed-in researchers.
Why is purity measured by LC-MS?
LC-MS separates the sample and identifies each component by its mass, so one run confirms identity and measures purity.
