Overview
KPV is a potent, naturally occurring tripeptide consisting of the amino acid sequence Lysine-Proline-Valine. Derived from the C-terminal fragment of alpha-melanocyte-stimulating hormone ($\alpha$-MSH), KPV retains the powerful anti-inflammatory properties of its parent molecule without inducing melanogenesis (pigmentation). In the field of advanced molecular immunology, KPV is recognized for its ability to translocate into the cell nucleus and modulate inflammatory signaling pathways, particularly by inhibiting NF-$\kappa$B (Nuclear Factor kappa-light-chain-enhancer of activated B cells). This provides researchers with a precise experimental tool to investigate the mitigation of cytokine storms, the restoration of intestinal barrier integrity, and the regulation of inflammatory responses in dermatological research models.
Our KPV is synthesized in an ISO 9001:2015 certified environment utilizing high-resolution Solid-Phase Peptide Synthesis (SPPS). We achieve an ultra-high chemical purity of ≥99%, verified by HPLC and Mass Spectrometry (MS). This rigorous production standard ensures the peptide is free from truncated sequences and residual chemical reagents, guaranteeing the consistency required for sensitive assays involving intestinal epithelial cells and systemic inflammatory biomarkers.
Research Applications & Mechanisms

Key Features & Quality Assurance
Pharmaceutical-Grade Lyophilization
Our proprietary vacuum-sealing process ensures the KPV powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid, clear reconstitution and protects the tripeptide from oxidative degradation during long-term storage.
High-Fidelity Sequence Integrity
Every batch undergoes strict Mass Spectrometry (MS) to confirm the exact Lys-Pro-Val sequence, ensuring maximal receptor interaction and reproducible data in cellular research.
Reconstitution & Storage
Reconstitution Guide
-
Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the KPV cake is at the base.
-
Solvent: Reconstitute with Sterile Water or Bacteriostatic Water.
-
Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.
Storage Protocols
-
Long-term: Store at -20°C (Maintains potency for up to 24 months).
-
Short-term: Stable at 2–8°C for up to 3 months.
-
Post-Reconstitution: Store at 2–8°C and utilize within 10-14 days for optimal results.
