Description
Product Overview:
KPV (Lys-Pro-Val) is a synthetic tripeptide derived from the C-terminal sequence of the endogenous hormone α-melanocyte-stimulating hormone (α-MSH). It is widely studied for its role in modulating inflammatory signaling pathways and cellular immune responses.
As a minimal bioactive fragment of α-MSH, KPV retains key biological activity associated with melanocortin signaling, particularly in relation to cytokine regulation and immune system modulation. Unlike the full α-MSH peptide, KPV provides a simplified structure that is frequently used in controlled laboratory environments to isolate specific signaling effects.
The KPV peptide offered by Proliven Labs is supplied as a high-purity (≥99.5%) lyophilized powder, manufactured under controlled conditions for consistency and reproducibility in research settings.
Functionally, KPV has been studied in a range of experimental models involving:
- Regulation of inflammatory cytokines (e.g., TNF-α, IL-6)
- Modulation of NF-κB signaling pathways
- Investigation of epithelial and mucosal barrier function
- Cellular response to inflammatory stimuli
Due to its targeted activity and small molecular structure, KPV is commonly utilized in in vitro studies and preclinical research models focused on inflammation and immune signaling.
Each vial contains 10mg of lyophilized KPV peptide, verified through batch-specific analytical testing.
This product is intended strictly for research use only (RUO). Not for human or veterinary use.

Research Applications
KPV peptide is widely utilized in research environments investigating inflammatory signaling pathways and immune system modulation. Its small size and defined mechanism make it particularly useful for isolating specific biological effects in controlled experimental systems.
Common research applications include:
Inflammatory Pathway Research
KPV has been studied for its ability to modulate key inflammatory mediators, including TNF-α and interleukin signaling pathways. It is frequently used in models examining cytokine-driven inflammation.
NF-κB Signaling Studies
KPV is known to influence NF-κB activation, a central transcription factor involved in inflammatory responses. This makes it a valuable tool in molecular biology and signaling pathway research.
Epithelial & Barrier Function Models
Preclinical studies have explored KPV in models of epithelial barrier integrity, particularly in gastrointestinal and dermal research systems.
Immune System Modulation Research
As a fragment of α-MSH, KPV is used to study melanocortin-related immune pathways and their effects on inflammatory regulation.
Cell Culture & In Vitro Models
KPV is commonly applied in cell-based systems to evaluate cellular responses to inflammatory stimuli and stress conditions.
This product is intended strictly for research use only (RUO). Not for human or veterinary use.
Mechanisms of Action
KPV exerts its biological activity primarily through modulation of inflammatory signaling pathways associated with melanocortin receptor activity.
Key mechanisms include:
NF-κB Inhibition
KPV has been shown to suppress activation of NF-κB, a transcription factor responsible for regulating inflammatory gene expression.
Cytokine Regulation
KPV reduces the production of pro-inflammatory cytokines such as TNF-α and IL-6 in experimental models, contributing to its role in inflammation research.
Melanocortin Pathway Activity
Derived from α-MSH, KPV interacts with melanocortin signaling pathways that are involved in immune modulation and inflammatory control.
Barrier Function Support
Studies suggest KPV may influence epithelial integrity and cellular junction stability in certain experimental systems.
These mechanisms position KPV as a targeted research compound for studying inflammation and immune signaling at the molecular level.
