KPV 5mg / 10mg (Alpha-MSH Fragment)

Certificate of Analysis (COA): Available Here

Chemical Identifier: Lysine-Proline-Valine (C-Terminal Fragment)

KPV is a naturally occurring tripeptide derived from alpha-melanocyte-stimulating hormone (alpha-MSH). In laboratory settings, this specific amino acid sequence (Lys-Pro-Val) is identified as the primary active component responsible for the immune-modulating properties of the parent hormone, without the pigment-stimulating side effects.

Tide Labs supplies high-purity, lyophilized KPV (5mg) for use in controlled research environments investigating cellular inflammatory pathways and microbial interactions.

Areas of Investigation

KPV is a subject of high interest in gastroenterology and dermatology research due to its specific interaction with inflammatory mediators:

• Systemic Inflammation (The NF-κB Pathway): Research suggests KPV may modulate the NF-κB pathway, acting as a "switch" that regulates immune response. Studies investigate its potential to stop inflammatory signals from entering the cell nucleus.
• Gut Health & Mucosal Barrier: In mouse models of colitis, KPV is observed for its interaction with the PepT1 transporter. Researchers utilize it to study the maintenance of intestinal lining integrity during stress.
• Antimicrobial Activity: In vitro (test tube) studies have shown KPV exhibits activity against specific bacteria and fungi (including C. albicans). It is a key variable in research regarding the body's natural defense against pathogens.
• Synergistic Pairing: KPV is frequently studied alongside BPC-157. Researchers often compare KPV’s anti-inflammatory mechanism against BPC-157’s tissue-repair mechanism.
